Abstract

Luminescence performance of YNbO 4 powder material co doped with Nd 3+ and Yb 3+ ions excited under 808 nm/980 nm laser diode (LD) is reported. Upconversion e mission spectr a of YNbO 4 Nd 3+ / Yb 3+ excited under 808 nm and 980 nm LD are recorded , and the results indicate that the strongest emission peak under 980nm excitation is locate d at 540 nm with green color , but located at 420 nm and 475 nm under 808 nm LD excitation The upconversion f itting results indicate that all of upconversion luminescence belong to two photon absorption process Moreover, downconversion emission spectr a in the scope from 900 nm to 1700 nm excited under 808 nm and 980 nm LD are also measured and luminescence process are analyzed..
