1. A method for identifying an article of manufacture comprising: producing a plurality of multilayer photonic structures, wherein each of the multilayer photonic structures comprises alternating layers of high index material and low index material such that each of the multilayer photonic structure
1. A method for identifying an article of manufacture comprising: producing a plurality of multilayer photonic structures, wherein each of the multilayer photonic structures comprises alternating layers of high index material and low index material such that each of the multilayer photonic structures has one more layer of the high index material than the low index material, and wherein each of the plurality of multilayer photonic structures has a unique intensity profile in a non-visible portion of an electromagnetic spectrum, and a substantially common intensity profile in a visible portion of the electromagnetic spectrum;incorporating one of the plurality of multilayer photonic structures that produces the unique intensity profile into a coating; andgenerating an electronic code corresponding to the unique intensity profile of one of the plurality of multilayer photonic structures. 2. The method for identifying an article of manufacture of claim 1 wherein the unique intensity profile is a reflectance profile, a transmittance profile, or a combination thereof. 3. The method for identifying an article of manufacture of claim 1 further comprising: loading the coating in a container; andapplying a coded indicia indicative of the electronic code to the container. 4. The method for identifying an article of manufacture of claim 1, wherein the unique intensity profile comprises a plurality of peaks each having a full width at half maximum value of about 100 nm or less. 5. A method for identifying an article of manufacture comprising: providing a coating comprising a multilayer photonic structure, wherein the multilayer photonic structure comprises alternating layers of high index material and low index material such that the multilayer photonic structure has one more layer of the high index material than the low index material, and wherein the multilayer photonic structure produces a unique intensity profile in a non-visible portion of an electromagnetic spectrum, and a substantially common intensity profile in a visible portion of the electromagnetic spectrum;applying the coating to at least a portion of an article of manufacture; andcorrelating an identifying indicia of the article of manufacture to the unique intensity profile. 6. The method for identifying an article of manufacture of claim 5 wherein the unique intensity profile is a reflectance profile, a transmittance profile, or a combination thereof. 7. The method for identifying an article of manufacture of claim 5 further comprising: generating an electronic code corresponding to the unique intensity profile; andcorrelating the identifying indicia of the article of manufacture to the electronic code. 8. The method for identifying an article of manufacture of claim 7 further comprising storing the electronic code in an electronic database such that the unique intensity profile is indexed according to the electronic code. 9. The method for identifying an article of manufacture of claim 8 wherein the electronic code comprises a digit and a quantized peak of the unique intensity profile corresponds to the digit. 10. The method for identifying an article of manufacture of claim 5 wherein the article of manufacture is a vehicle. 11. The method for identifying an article of manufacture of claim 10 wherein the identifying indicia is at least one of a manufacturer, a vehicle category, a manufacturing division, a vehicle make, a body style, a vehicle model, and a sequential number. 12. The method for identifying an article of manufacture of claim 11 wherein the coating is applied to a frequently impacted area of the vehicle. 13. The method for identifying an article of manufacture of claim 5 wherein the coating is a paint, a clear coat, or a sheet. 14. A method for identifying an article of manufacture comprising: collecting a sample from an article of manufacture, wherein the sample comprises a multilayer photonic structure, wherein the multilayer photonic structure comprises alternating layers of high index material and low index material such that the multilayer photonic structure has one more layer of the high index material than the low index material, and wherein the multilayer photonic structure has a unique intensity profile in a non-visible portion of an electromagnetic spectrum, and a substantially common intensity profile in a visible portion of the electromagnetic spectrum;transmitting a reference light to the multilayer photonic structure to produce the unique intensity profile;detecting the unique intensity profile;querying an electronic database to determine identifying indicia of the article of manufacture;retrieving the identifying indicia of the article of manufacture from the electronic database to identify the article of manufacture. 15. The method for identifying an article of manufacture of claim 14 wherein the unique intensity profile is a reflectance profile, a transmittance profile, or a combination thereof. 16. The method for identifying an article of manufacture of claim 14 further comprising retrieving an electronic code indicative of the unique intensity profile, wherein the electronic database is queried with the electronic code. 17. The method for identifying an article of manufacture of claim 14 wherein the sample is removed from an object after a collision with the article of manufacture. 18. The method for identifying an article of manufacture of claim 14 further comprising quantizing the unique intensity profile. 19. The method for identifying an article of manufacture of claim 14 wherein the identifying indicia is a vehicle identification number. 20. The method for identifying an article of manufacture of claim 14 wherein the identifying indicia is at least one of a manufacturer, a vehicle category, a manufacturing division, a vehicle make, a vehicle model, a body style, and a sequential number.
