Enhanced 1.8 μm emission in Er 3+ /Tm 3+ co-doped lead silic

发布时间：2022-01-26 16:25

　　A detailed study of the fluorescence emission properties and energy transfer mechanism in Er³⁺/Tm³⁺ co-doped lead silicate glasses was reported. Enhanced near infrared 1.8 μm and visible up-conversion emissions were investigated under 808 and 980 nm excitations, respectively. The energy transfer mechanism between Er³⁺ and Tm³⁺ was analyzed according to the absorption spectra, the emission spectra and the level structures of Er³⁺ and Tm^3...
