Photoluminescence Properties of LaB3O6:Sm3 Phosphor

The Orange- red emitting LaB3O6:Sm3+phosphor was successfully synthesized via solution combustion method. The structure of the prepared LaB3O6:Sm3+phosphor was confirmed by powder XRD analysis and its photoluminescence properties has been studied under ultraviolet (UV) excitation (200–450 nm). The XRD pattern of prepared LaB3O6:Sm3+phosphor is well matched with available standard ICDD file with card no-1510925.The PL excitation of prepared phosphor was monitored at 597 nm while emission was monitored at 405 nm. The CIE co-ordinates were calculated and obtained in orange- red region.
