摘　　要：制备了多孔掺铒铌酸锂材料,并研究了其3波长可见上转换荧光特性.在980 nm连续光激发下发射峰中心波长分别为660、550和450 nm.通过相干背散射法测得多孔铌酸锂的传输平均自由程在亚微米范围,这使得制备的多孔掺铒铌酸锂适用于可见光多波长上转换随机激光.A porous erbium doped lithium niobate was fabricated for studying upconversion luminescence to three wavelengths in the visible. The emission bands excited by a 980 nm diode laser were centered at 660, 550 and 450 nm, respectively. The transport mean free path was found to be in the submicron range in coherent backscattering measurements. This makes the material suitable for an upconversion random laser emitting at multiple wavelengths in the visible.
