Optical Properties of Erbium-Doped Tellurite Glasses: A Review and Bibliometric Study

Abstract

The aim of this paper is to review the optical properties of tellurite glasses doped by erbium and describe their bibliometric study about it. The research documents on of optical properties of tellurite glasses doped by erbium in the Scopus database are 115, start from 1999 until now. The visualization of the research assisted by VOSviewer software. There are three clusters: (1) red cluster for the optical properties begin from the fabrication process until the characterization of glasses based on the geometrical optics phenomena, (2) green cluster for the emission spectra until the analysis using McCumbers Theory, and (3) erbium-doped tellurite glasses optical properties based on energy transfer and XRD analysis on the blue cluster. Based on the Scopus documents, not too many researchers are concerned with researching erbium-doped tellurite glasses, never more than 12 documents per year. However, the researchers are consistent to explore further exploring the characteristics of the optical properties of glass exposed to erbium ion for laser applications.The research funding shows that the tellurite glasses doped by erbium are being developed for laser applications.
