Yb3+/Tm3+ co-doped germanate-tellurite glass: conversion luminescent and temperature-sensing characteristics

“…Optical materials doped rare earth ion are widely used in laser technology [1,2] , optical temperature sensing [3,4] and fiber optic communication [5] . Since glass materials have the advantages of low manufacturing cost, simple preparation process and stable product quality, glass matrices are often used to study the luminescence and temperature characteristics of the rare earth ions, mainly including fluoride glass, germanate glass, tellurite glass and silicate glass.…”

Effects of melting temperature on color-changing in germano-tellurite niobate glass

“…However, compared to other oxide glass systems, for example, silicate or germanate glass systems, tellurite glasses generally present low glass transition temperature (Tg) and onset of crystallisation temperature (Tx) causing their poor thermal stability, which can be a drawback. Introducing GeO2 into tellurite glass can improve their thermal performances, and thus germano-tellurite glasses are widely investigated [7][8][9][10]. Among various kinds of germano-tellurite glasses, germano-tellurite niobate glasses have gained significant interest because of their applications in lasers and optical devices [7,[11][12][13][14][15].…”

Thin films based on Er>sup<3+>/sup< doped germanate-tellurite nanoglasses for Plasmonics

“…Furthermore, Er 3+ ions can act as centers of phonon scattering, which means they can slow down phonons and increase their energy. 81 Furthermore, the presence of Er 3+ ions can affect the structure of the glassy lattice, leading to increased stiffness and changing the frequency and amplitude of phonon vibrations, increasing phonon energy 82 . The cyan region in Figure 16.a highlights the E ph region.…”
