This study aimed to enhance the optical properties on neodymium oxide (Nd2O3) and erbium oxide (Er2O3) doped tellurite-based glass coated with graphene oxide (GO). The two series of  tellurite glasses with chemical composition of {[(TeO2)0.7 (B2O3)0.3]0.7 (ZnO)0.3}1?y (Nd2O3)y and  {[(TeO2)0.7 (B2O3)0.3]0.7 (ZnO)0.3}1?y (Er2O3)y with varying concentrations of Nd³+ and Er³+ ions from y=0.005, 0.01, 0.02, 0.03, 0.04, and 0.05 mol% were  prepared and coated with GO using melt-quenching and spray coating methods. The physical,  structural and optical properties of prepared glasses were characterized using densimeter, scanning  electron microscopy (SEM), X-ray diffraction (XRD), Fourier transform infrared (FT-IR),  Ellipsometer, and ultraviolet- visible (UV- Vis) spectrophotometer. The structural analysis  determined by XRD pattern proved an amorphous structure for the glass samples. The obtained results  through FT-IR analysis showed the formation of non-bridging oxygen.....

This study aimed to improve the optical properties of reduced graphene oxide- and carbon nanotubes-coated tellurite glass doped with erbium oxide nanoparticles denoted as ZBTEr(NPs)-rGO and ZBTEr(NPs)-CNTs. Two sets of glass series were synthesized by melt-quenched technique with chemical composition of (0.47(1-y))TeO2+(0.2(1- y))B2O3+(0.29(1-y))+ZnO+Er2O3(y) wherein, y = 0.005, 0.01, 0.02, 0.03, 0.04, and 0.05 mol% Er2O3 nanoparticles. Tellurite-based glass was deposited with rGO and CNTs onto the glass surfaces by spray-coated technique. The physical, morphological, structural, and optical properties of ZBTEr(NPs)-rGO and ZBTEr(NPS)-CNTs glasses were characterized via densimeter, scanning electron microscopy (SEM), energy dispersive X-ray (EDX), transmission electron microscopy (TEM), X-ray diffraction (XRD), Fourier transforminfrared (FT-IR), micro-Raman spectroscopy, ultraviolet-visible (UV-Vis) spectrophotometer, and photoluminescence. SEM micrographs revealed morpholog.....
