摘要:
The optical and physical properties of a low-voltage phosphor,SrGa2S4:Eu2+,are reviewed. This phosphor has excellent chromaticity and high luminous efficiency at excitation voltages<3 kVand at high drive current(∼100 &mgr;A/cm2).At high current densities this phosphor was found to have superior saturation properties compared to current phosphors. This is attributed to the fast decay time of this phosphor, which is expected to enhance its resistance to saturation. Recent studies show that this phosphor has good maintenance properties. ©1998 American Institute of Physics.
