摘要：

Influence of Nd3+ concentration on up-conversion fluorescence colour in YVO4 triple doped with Ho3+, Yb3+ and Nd3+ ions excited by 980 nm laser diode was investigated. A serials of NdxHo0.02 Yb0.05Y0.93-xVO4 (where x=0, 0.25, 0.5, 0.75 and 1 at%) crystalline materials were synthesised by a solid state reaction. Excitation in the F-2(5/2) bands of Yb3+ produced a strong red and a weaker green emissions at 300 K for Ho3+,Yb3+:YVO4 whereas for Ho3+,Yb3+,Nd3+:YVO4 a strong green emission was observed. Concentration dependence studies indicated that Nd3+ concentrations had significant influences on up-conversion mechanisms and emission colour. (C) 2012 Elsevier B.V. All rights reserved.
