Improved self-cleaning and spectral features of erbium doped tellurite glass with titania nanoparticles sensitization
The effects of Titania nanoparticles (TiNPs) sensitization on the self-cleaning, spectral, and physical properties of erbium-doped tellurite glass were determined. Five glass samples with composition (69-x)TeO2-20ZnO-10Na2O-1Er2O3-(x)TiO2, where x = 0.0, 0.1, 0.2, 0.3 and 0.4 mol% were synthesized u...

The effects of Titania nanoparticles (TiNPs) sensitization on the self-cleaning, spectral, and physical properties of erbium-doped tellurite glass were determined.
