Spectroscopic properties of Tm3+ in fluorophosphate glasses

Synthesis and infrared spectroscopic properties of Tm3+-doped phosphate glasses

“…The Judd-Ofelt intensity parameters calculated for Tm 3+ -doped KCaAlP glass (0.75 mol% Tm 2 O 3 ) are given in Table 3 together with intensity parameters of Tm 3+ in different oxide and fluoride glasses as reported in Refs. [19][20][21][22][23][24][25][26][27]. The comparison between the different values reported in Table 3 shows that Ω 4 and Ω 6 determined for Tm 3+ -doped KCaAlP glass are comparable to those obtained in fluoride glasses while Ω 2 is higher in oxide glasses, it varies as:…”

Mechanical and ∼2μm emission properties of Tm3+-doped GeO2–TeO2 (or SiO2)–PbO–CaO glasses

“…The spectroscopic properties of Tm-doped silicate, fluorophosphate, germanate, and tellurite glasses or crystals have been studied for decades [1][2][3][4][5]. Most studies have been focused on the development of fiber laser systems capable of delivering efficient high-power output at a wavelength of 2 lm because of its applications in the area of remote sensing, medical surgery, environmental sensing, and light sources for efficient mid-IR generation [6][7][8][9].…”

Upconversion properties of the Er3+ doped 20GaF3–15InF3–20CdF2–15ZnF2–20PbF2–10SnF2 glasses

“…The starting materials were Ga 2 in a platinum crucible for 1 h. Glass was melted at 800°C in a platinum crucible with a resistance furnace, after complete melting, the glass melt was cast by pouring into brass moulds which were preheated. The whole melting process was under a dry nitrogen atmosphere.…”

“…Compared with glasses based on oxide, fluoride glasses have lower phonon energy and have received much attention. Er 3+ doped fluorophosphate glasses [2,3], fluorozirconate glasses [4,5], fluoroaluminate glasses [6,7] all show good properties in green emission. The phonon energy in zirconium-free heavy metal fluoride glasses is even lower.…”
