摘要/Abstract

摘要： 测量了Pr³⁺∶Y₂SiO₅晶体的吸收谱, 标定了室温下Pr³⁺在Y₂SiO₅晶体4f²组态内的能级. 利用579 nm激光激发Pr³⁺∶Y₂SiO₅晶体, 观察到480~515 nm上转换荧光带. 运用时间分辨激光光谱技术测量了³P₀能级的上转换荧光衰减曲线. 通过研究上转换荧光的衰减曲线、吸收谱、激发谱和上转换荧光强度与泵浦激光单脉冲能量的关系, 确定了以¹D₂为中间态的能量转移上转换主要是上转换机制. 

Abstract: The blue upconversion via Pr³⁺∶Y₂SiO₅ crystals under excitation of 579 nm laser was investigated at room temperature. The upconverted luminescence band at the blue region from 480 nm to 515 nm was obtained with orange laser excitation. The upconversion mechanism was studied by observing the absorption and excitation spectra, the dependence of upconverted luminescence on pump power, and the decay profile of the upconverted luminescence. It was found that the upconverted luminescence was produced by energy transfer upconversion (ETU) process with ¹D₂ as intermediate state.

Key words: Pr³⁺∶Y₂SiO₅ crystal, orange-to-blue frequency upconversion, energy transition upconversion
