Paper Abstract

Lumogen Yellow S 0790 is a commercial pigment based on azomethine and is used for enhancing charge-coupled device (CCD) for detecting ultraviolet radiation. It's used as a wavelength up-shifter, whereby short wavelength ultraviolet (UV) light that is absorbed by the material is rapidly re-emitted with longer wavelengths in the visible spectra, for improving the spectral response of CCD detectors. In this work we research on differences of the crystallized sample and the re-crystallized sample in crystal structure, morphology and optical properties, including laser-induced fluorescence excitation spectrum, emission spectrum and Raman spectra. The results show that re-crystallized Lumogen sample has better crystalline structure on the application of ultraviolet sensitizer. By using the re-crystallized as-deposited Lumogen films on glass substrate in front of the CCD detector, ultraviolet can be detected and quantized better.
