材料双光子吸收高温固相法 ZnF2基质稀土上转换 materials two-photon absorption high temperature solid state reaction ZnF2 substrate rare earth up-conversion

摘要

为了研究ZnF2作为基质材料、稀土离子Yb3+和Er3+共掺摩尔分数不同时的发光性能, 采用高温固相法, 在820℃时制备稀土掺杂ZnF2样品, 并对各个样品进行上转换发射光谱测试。将激发功率与上转换发射功率进行曲线拟合, 确定Yb3+和Er3+光子吸收过程。结果表明, 在980nm半导体激光器激发下, 样品在可见光区域内存在533nm,555nm和655nm 3个上转换发射峰, 发射的红光强度大于绿光强度, 吸收光子数目依次为1.73,1.75,1.88, 确定3个发射峰均对应于双光子吸收。此研究说明稀土离子掺杂ZnF2材料将在上转换红色荧光粉领域有重要的应用前景。

Abstract

In order to study luminescent properties of rare earth ions Yb3+ and Er3+ with different co-doped molar fractions and ZnF2 as matrix material, by using high temperature solid state method, samples of rare earth doped by ZnF2 at 820℃ were prepared and the up-conversion emission spectra was measured. Yb3+ and Er3+ photon absorption processes were determined by fitting the excitation power and up-conversion power. The results show that under the excitation of 980nm laser diodes, the samples have 3 up-conversion emission peaks of 533nm, 555nm and 655nm in the visible region. The intensity of red light is greater than that of green light.The number of the absorbed photons is 1.73, 1.75, and 1.88. 3 emission peaks are correspond to two-photon absorption.The materials of rare earth ion doped by ZnF2 have important application prospects in up-conversion red phosphors.
