Title: NIR to visible upconversion emission in Tm{sup 3+} doped Na{sub 2}Y{sub 2}B{sub 2}O{sub 7} powder phosphor

Abstract

Tm{sup 3+} ions doped Na{sub 2}Y{sub 2}B{sub 2}O{sub 7} powder phosphor has been synthesized through combustion method. Crystal structure and phase of the prepared sample have been investigated by powder X-ray diffraction (XRD) analysis. Upconversion emission bands in the 400-900 nm range under the excitation of 980nm diode laser have been acquired, and involved upconversion mechanism has been discussed with the help of a suitable energy level diagram. The colour coordinate of developed phosphor has been calculated by CIE chromaticity diagram. Present phosphor can be used in fabrication of upconverting LEDs.
