제안 방법
- I-V characteristics of the hybrid detector and a-Se detector were measured to investigate the electrical properties of both detectors. The dark currents flowing in the a-Se detector and hybrid detector were measured without x-ray inadiation during applying voltage at an interval of 2 V/jt/m from 2 to 10 V/㎛.
- In this work, a hybrid detector composed of a ZnS:Ag phosphor layer and a-Se photoconductive layer was fabricated as a new x-ray detector structure to improve the low x-ray sensitivity of a-Se based x-ray detector. The dark current and the x-ray sensitivity of the hybrid and selenium detector were measured as a function of applied voltages.
대상 데이터
- Both deuterium discharge tube for the ultraviolet(UV) region and halogen lamp for the visible-near infrared region is used as light sources, and light sources are automatically turned at about 350 nm. Detectors are composed of PM tube for the UV-Visible region and cooled PbS type cell for the near-infrared region; the each detector is automatically exchanged at about 800 nm. The light absorption was measured at a wav이ength of 200-800 nm 디vith a scan rate of 600 nm/min.
- nm. Experimental results were obtained on ZnS:Ag (200 ”m) and a-Se(l //m) deposited on ITO glass. Photoluminescence characterization of the ZnS:Ag phosphor layer shows a broad emission peak centered at about 450 nm, which matches the sensitivity spectrum of selenium.
- The PL measurement system is composed of a He-Cd Laser(Spirox Holding) and double monochrometer (SPEX 1403). UV light excited from He-Cd laser (55 mW) is illuminated on the surface of ZnS:Ag phosphor layer (200 ㎛).
