|Title:||IR emission of Er<sup>3+</sup> ion-doped fluoroborotellurite glass for communication application|
|Keywords:||Materials Science;Physics and Astronomy|
|Abstract:||We have successfully synthesized Er3+ ion-doped TeO2-B2O3-ZnF2-BaO using conventional melt and quenching technique to explore their possible future application. The physical properties were determined by their density and molar volume, while the structural properties were observed by FTIR spectra. The optical absorption spectra and emission spectra were measured to study their optical and photoluminescence properties. The optical absorption spectra were measured between 400 to 1800 nm. It shows the hypersensitive transition at 521 nm due to the 4I15/2→2H11/2 transition. The intense emission was shown in the peak of 1541 nm excited by 521 nm due to 4I13/2 to 4I15/ 2 transition. From the analysis of Judd-Ofelt theory, it is found that 1.5 mol% Er2O3 in the glass system possesses JO trendline Ω2 > Ω4 > Ω6 and 2.94 × 10−21 cm2 stimulated emission cross-section with the long radiative lifetime around 12.19 ms. The gain cross-section of prepared glass calculated using the Mc Cumber theory reveals the inversion population of prepared glass at γ≥0.4. It could be concluded from all results that 1.5 mol% Er2O3 doped fluoroborotellurite glass have a high potential for future communication application such as IR optical amplifier, IR laser, and WDM network system in C and L communication band.|
