Open publisher page 8 citations

Abstract

The photoluminescence and cathodoluminescence of phosphor were optimized with the process and chemical variables (activators, fluxes and reaction temperature) used in solid state reaction. Firing the powder with flux at for 2hr gave the highest photoluminescence efficiency under near-UV excitation and the highest cathodoluminescence efficiency of 20.1 lm/W at 2 kV and 33.3 lm/W at 10 kV. The suitability of for application as a phosphor in LCDs and FEDs is discussed.
