A novel erbium ion doped zinc fluoride glass was prepared. 2.7μm emission and transmittance properties together with thermal ability were investigated. An enhanced 2.7μm emission was observed by introducing ZnF2 in the ZrF4-based fluoride glass. Meanwhile, the J-O parameters and branching ratios (β) of Er3+-doped zinc fluoride glass were calculated and analyzed. The present Er3+-doped zinc fluoride...
With a 980nm laser diode (LD) pumped, the sensitized effect of Yb 3+ ions on 2.7μm emission properties and energy transfer mechanism in Yb 3+ /Er 3+ co-doped tungsten–tellurite glass were investigated in present paper. Based on absorption spectra, Judd–Ofelt parameters and radiative transition probabilities were calculated and analyzed. The emission spectra were tested and...
