Abstract
The photoluminescence and cathodoluminescence of SrGa2S4:Eu phosphor were o ptimized with the process and chemical variables (activators, fluxes and re action temperature) used in solid state reaction. Firing the powder with fl ux at 800 degrees C for 2hr gave the highest photoluminescence efficiency u nder near-UV excitation and the highest cathodoluminescence efficiency of 2 0.1 lm/W at 2 kV and 33.3 lm/W at 10 kV. The suitability of SrGa2S4:Eu for application as a phosphor in LCDs and FEDs is discussed.
