Structural, Optical and Dilute Magnetic Semiconducting Properties of Gd Doped SnO₂ Nanoparticles

Structural, optical and magnetic properties of Cu doped CeO2 nano powders synthesized by solid state reaction

“…The presence of defects has been seen to impact the structural and functional aspects of Ceria nanoparticles, including their ability to facilitate oxygen transport, catalytic activity, energy storage capabilities, and physical characteristics, among others, author reports the Mndoped CeO 2 samples exhibit a notable emission of fluorescence with peak wavelengths at 490 and 520 nm, which can be attributed to defects mediated by oxygen. Defects such as oxygen vacancies are frequently ascribed as the underlying cause of deep-level emissions observed in various oxide materials [48]. The observed phenomenon can perhaps be attributed to the presence of oxygen vacancies inside films with electrical energy levels that are situated below the Ce 4 f band.…”
