THE EFFECT OF ZINC CONTENT ON THE ENHANCEMENT Er3+-Yb3+ LUMINESCENCE PROPERTIES IN THE SILICATE GLASS MATRIX

Abstract

Glasses doped with Er and Yb show strong luminescence around 1530 nm, which makes them attractive luminophores

Er3+/Yb3+ doped active optic Y splitter realized by diffusion waveguides with Ag+—Na+ ion exchange

“…. To achieve the highest possible amplification of the optical amplifier, it is possible to increase the luminescence properties of the substrate material by adding ZnO to the glass matrix (Vytykacova et al 2018). For research of optical amplifiers fabricated by ion exchange technology, GZ4 silicate glass containing 0.25 at.…”

“…It can be seen from the measurement results that the Zn admixture has a positive effect causing an increase in luminescence intensity. The Zn acts as a separator of Er 3+ -Yb 3+ ions in the glass matrix, which limits the energy exchange between ions and prevents clustering of activator atoms (Vytykacova et al 2018). As in the case of rare-earth doping, it is not possible to increase the concentration of Zn in the glass matrix without undesirable consequences, such as the phase separation effect causing the low optical quality of the glass, which is unacceptable for the application of optical waveguides.…”
