Abstract: In this work enhancement of SrF2:Ce nanophosphor which was synthesized by co-precipitation method is presented. Synthesized phosphor was characterized by SEM and PL measurements. Average particle size is found to be in the range 150nm-200 nm and PL studies showed emission peaks at 330nm,360nm,380nm when samples were excited by 254nm. The observed double humped emission is characteristic emission of Ce3+ similar to that observed in bulk SrF2. However under identical condition it is observed that intensity of emission get enhanced and is about nearly 1.75 times in Ce3+ doped SrF2 nanocrystals than the bulk. [ABSTRACT FROM AUTHOR]
