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 ...
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 ...
Synthesis and characterization of long persistent phosphors using combustion method

Colen, Manaka Mmakgabo (2015)

In this work, alkaline earth aluminate phosphors doped with rare-earth ions and manganese were synthesized using combustion method. Several characterization techniques were used to study the structural and luminescent ...
