Abstract

ZnS electroluminescent phosphors were prepared by high temperature (1100℃) solid state reaction, subsequently milling for some time (t=0-180min) and the final low temperature annealing process (750℃). The as-synthesized phosphors were characterized by X-ray powder diffraction, UV-Vis diffuse reflectance spectra, scanning electron microscope and photoluminescence spectra. Electroluminescence performance was investigated on the screen-printing electroluminescent lamp at 100V and 400Hz. Increased milling time leads to intensity reductions and width increases of some diffraction peaks, and results in slight red-shifts of the absorption edges. Photoluminescence brightness declines about 58% after milling for 180 min while electroluminescence brightness increases from 14.39cd/m2(t=0min) to the peak value 90.13cd/m2(t=160min). The changes of photoluminescence and electroluminescence performances originate from the defects in the microstructure induced by milling.

Key words： photoluminescence; electroluminescence; ZnS; milling
