The development of undoped alkaline silicate and doped alkaline aluminate phosphors for white phosphorescence, dosimetry, and persistent luminescence applications

Manaka, Mmakgabo Colen (2022-03)

The undoped SrSiO3/SiO2 phosphors prepared by both co-precipitation and hydrothermal methods at different Sr/Si molar ratios are reported. Undoped and Mn doped BaAl2O4 phosphor synthesized using combustion method are ...
Investigation of up and down-converting rare earth ions doped ZnTiO3 for photovoltaic applications

Mofokeng, Sefako John (2019-10)

We are living in an age where the demand for energy is growing rapidly. This means that supplies to easily accessible oil and natural gas is unlikely to keep up with the demand as times goes on. The world will have to ...
Luminescence investigation of zinc oxide nanoparticles doped with rare earth ions

Kabongo, Guy Leba (2013-11)

Un-doped, Tb3+ as well as Yb3+ doped ZnO nanocrystals with different concentrations of RE3+ (Tb3+, Yb3+) ions were successfully synthesized via sol-gel method to produce rare earth activated zinc oxide nanophosphors. The ...
