摘要
采用高温热熔融法制备了CdTe量子点掺杂的硅酸盐玻璃, 测试了其拉曼、吸收和发射光谱, 验证了量子点掺杂玻璃的量子尺寸效应。在飞秒激光（800 nm和960 nm）激发下, CdTe量子点掺杂玻璃产生了上转换荧光, 证明了其为双光子吸收诱导发光, 发现双光子荧光对激发波长有一定的范围要求, 测得CdTe量子点掺杂玻璃的非线性吸收系数可达3.62×10-11 m/W。
Abstract
The silicate glass doped with CdTe quantum dots is prepared by the high temperature melt-quenching technique and the Raman, absorption and emission spectra are tested. The quantum size effect of quantum dot doped glass is verified. The up-conversion fluorescence of the CdTe quantum dot doped glass is excited by 800 nm and 960 nm femtosecond lasers, which is confirmed to be two-photon absorption induced luminescence and the two-photon fluorescence possesses a requirement for a certain range of wavelengths. The nonlinear absorption coefficient of the CdTe quantum dot doped glass is obtained up to 3.62×10-11 m·W-1.
