    Abstract: Improving the optical properties of copper oxide nanoparticles (CuO NPs) in tellurite glass is crucial for the development of efficient solid state laser. In this work, we report the results of structurally-induced transitions in melt-quench synthesized CuO NPs integrated Er2O3 doped multicomponent tellurite glasses. Based on the predecessors’ work...

    Abstract: Carbon nanotubes (CNTs) have attracted increasing attention due to their superior physical and chemical properties such as their high electrical and thermal conductivity, great specific area, etc. Scanning electron microscopy on commercial CNTs was optimized. Based of Rayleigh level, the resolution of optical system was induced by substituting para... Show More
