연합인증

연합인증 가입 기관의 연구자들은 소속기관의 인증정보(ID와 암호)를 이용해 다른 대학, 연구기관, 서비스 공급자의 다양한 온라인 자원과 연구 데이터를 이용할 수 있습니다.

이는 여행자가 자국에서 발행 받은 여권으로 세계 각국을 자유롭게 여행할 수 있는 것과 같습니다.

연합인증으로 이용이 가능한 서비스는 NTIS, DataON, Edison, Kafe, Webinar 등이 있습니다.

한번의 인증절차만으로 연합인증 가입 서비스에 추가 로그인 없이 이용이 가능합니다.

다만, 연합인증을 위해서는 최초 1회만 인증 절차가 필요합니다. (회원이 아닐 경우 회원 가입이 필요합니다.)

연합인증 절차는 다음과 같습니다.

최초이용시에는
ScienceON에 로그인 → 연합인증 서비스 접속 → 로그인 (본인 확인 또는 회원가입) → 서비스 이용

그 이후에는
ScienceON 로그인 → 연합인증 서비스 접속 → 서비스 이용

연합인증을 활용하시면 KISTI가 제공하는 다양한 서비스를 편리하게 이용하실 수 있습니다.

Abstract ▼ AI-Helper 아이콘AI-Helper

In the geochemical field, the chemical speciation of hexavalent uranium (U(VI)) has been widely investigated by performing measurements to determine its luminescence properties, namely the excitation, emission, and lifetime. Of these properties, the excitation has been relatively overlooked in most ...

제안 방법

  • (Andor, SR-303i). The time-resolved luminescence spectra were recorded by accumulating 100 laser pulses using two different gated intensified charge-coupled devices (ICCD, Andor, DH-720/18U-03 iStar 720D for λex = 266, 355, and 410-500 nm, and DH320T-18U-93 for λex = 220-400 nm) attached to the outlet ports of the spectrographs. All spectra were measured using a 1,000 μs gate width (tw) and varying gate delay time (td).

대상 데이터

  • A high-purity grade silica gel with a particle size of 40-63 μm (Sigma-Aldrich 227196) was used. The pore size of the silica gel reported by the manufacturer was approximately 6 nm (0.
  • Excitation spectra were recorded by scanning the excitation wavelength from 200 to 500 nm with a 2 nm step. Emission spectra were measured using a CCD in the wavelength range of 242-823 nm, with a resolution of 1.16 nm. The integration times were 5 and 0.
  • sources. Two OPOs were operated at different wavelength ranges of 220-400 nm (Continuum, Horizon I) and 410-500 nm (OPOTEK, Vibrant B). All lasers were operated at a repetition rate of 10 Hz.
