چکیده
In this work we present a comparison of the quantum efficiencies (QE) of the 411312+ 411512 transition of Er3+ in ZBLAN (58 ZrF4-18 BaF2-5.5 LaF3-3 A1F3-15 NaF), BIGaZYT (30 Be2-18 InF3-20 ZnF2-10 YF3-10 ThF4-12 GaF3), and silica (67.7 Si02-16.2 SiO-11.1 Ca0-5 A1203) glasses obtained by photoacoustic spectroscopy. In the case of ZBLAN and BIGaZYT glasses, the method takes into account the 4111, + 4F712 excited state absorption.

2.7 μm emission of high thermally and chemically durable glasses based on AlF3
AlF3-based glasses (AlF3-YF3-CaF2-BaF2-SrF2-MgF2) with enhanced thermal and chemical stability were synthesized and compared with the well-known fluorozirconate glass (ZBLAN). The 2.7 μm mid-infrared emission in the AlF3-based glasses was also investigated through the absorption and emission spectra. Both the temperature of glass transition and the characteristic temperatures (ΔT, Hr, k(gl)) of...

Er3+-doped fluorozirconate (ZrF4-BaF2-YF3-AlF3) and oxyfluoroaluminate glasses are successfully prepared here. These glasses exhibit significant superiority compared with traditional fluorozirconate glass (ZrF4-BaF2-LaF3-AlF3-NaF) because of their higher temperature of glass transition and better resistance to water corrosion. Judd-Ofelt (J-O) intensity parameters are evaluated and used to comp...
متن کاملSpectral Properties of Er3+/Tm3+ Co-Doped ZBLAN Glasses and Fibers
A series of Er3+/Tm3+ co-doped fluoride (ZBLAN) glasses and fibers was prepared and their fluorescence spectra was measured under excitation at 793 nm and 980 nm. Correlation between the self-absorption effect of rare-earth ions and the shift of the emission peak was investigated. With the increasing length of fiber, the emission peaks red-shift when self-absorption occurs at the upper level of...

2.0 μm emission properties of Er3+/Ho3+ codoped silicate glasses were investigated pumped by 980 nm LD. Absorption spectra were determined. Intense mid-infrared emissions near 2 μm are observed. The spectral components of the 2 μm fluorescence band were analyzed and an equivalent model of four-level system was proposed to describe broadband 2 μm emission. Low OH- absorption coefficient (0.23 cm...
