Description
Summary:Phosphor material CaMgAl10O17 with varying concentration of rare earth Ce3+ synthesis by combustion method at 500°C. The synthesized phosphor material characterized for their crystallinity and nature by XRD measurements. The photoluminescence measurements of phosphor exhibit mainly two PL spectra 382nm and 575 nm in blue and red region, respectively, this is due to crystal field and covalence effect. These results show that concentration quenching occur at 5mol° of Ce dopant. The results suggest the possibility of utilizing as a phosphor may be in solid state lighting.
