Physical, structural and spectroscopic analysis of tellurite glass containing natural magnetite Fe3O4 nanoparticles

This paper reports the influence of the embedment of natural magnetite (Fe3O4) nanoparticles (NP) in tellurite glass containing Er3+ ions. Significance results on physical, structural and emission properties obtained from varying Fe3O4 nanoparticles in the glass network are well discussed. In this w...
