Sonochemical synthesis of optically active fluorides
(Belgrade : Institute of Technical Sciences of SASA, 2021)
Up-conversion is the optical property of materials which have ability to convert low energy photons (usually from infrared spectrum) into higher energy photons (from visible spectrum). Such compounds, usually lanthanide ...
Optically active SrGd2O4 phase: Yb3+/Ho3+ and Yb3+/Tm3+ co-doping
(Belgrade : Serbian Ceramic Society, 2022)
Optically active materials have a wide range of applications. The phenomenon of light conversion includes two main types: up-conversion, which is the ability of convertion lower energy photons into the ones with the higher ...
Enhancement of up-conversion luminescent characteristics of Yb3+/Ho3+ co-doped Bi3+ based SrGd2O4 nanoparticles
(Belgrade : Institut za multidisciplinarna istraživanja, 2023)
In this investigation, samples of SrGd2O4 doped with different Yb3+ (2, 4, 6 at.%) ions and constant Ho3+ (1 at.%) and Bi3+ (2 at.%) concentrations were prepared. The sol-gel method with glycine as a fuel and citric acid ...
