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 ...
Structural and luminescence properties of NaYF4:Yb3+/Er3+ and NaGdF4:Yb3+/Nd3+ nanocrystals for possible application in photovoltaic solar cells

Thokwane, Pebetsi (2023-04)

NaYF4:Yb3+/Er3+ and NaGdF4:Yb3+/Nd3+ nanocrystals were prepared using a solution combustion (SC) method and their properties were evaluated for potential use as photon harvesters in photovoltaic solar cells (PSCs). The ...
Study of Structural and Optical Properties of Undoped and Rare Earth Doped TiO2 Nanostructures

Talane, Tsholo Ernest (2017)

Un-doped, Er3+ doped (TiO2:Er3+) as well as Er3+/Yb3+ co-doped (TiO2:Er3+/Yb3+) nanocrystals with different concentrations of RE3+ (Er3+, Yb3+) were successfully synthesized using the sol-gel method. The powder X-ray ...
