K.G. Tshabalala,So-Hye Cho,Jong Keuk Park,Shreyas S. Pitale,I.M. Nagpure,Robin E. Kroon,H.C. Swart,Odireleng M. Ntwaeaborwa +7 more
TL;DR: In this article, a combustion method using urea as fuel was used to improve the optical properties and crystallinity of zinc aluminate (ZnAl 2 O 4 ) nanocrystals.
Journal ArticleDOI
Enhanced green emission from UV down-converting Ce3+–Tb3+ co-activated ZnAl2O4 phosphor
TL;DR: In this paper, an enhanced down-converted green emission associated with the 5D4→7F5 transitions of Tb3+ ions was observed at 543 nm from the ZnAl2O4:Ce3++ powders.
Journal ArticleDOI
Effect of Tb3+ concentration on the structure and optical properties of triply doped ZnAl2O4:1% Ce3+,1% Eu3+,x% Tb3+ nano-phosphors synthesized via citrate sol-gel method
Setumo Victor Motloung,K.G. Tshabalala,Robin E. Kroon,Thulani Thokozani Hlatshwayo,Mbuso Mlambo,Siyasanga Mpelane +5 more
TL;DR: Ce3+, Eu3+ and Tb3+ singly and triply doped ZnAl2O4 nano-powders were successfully synthesized via the citrate sol-gel method.
Journal ArticleDOI
Effect of annealing temperature on nano-crystalline TiO2 for solar cell applications
T.D. Malevu,Benard S. Mwankemwa,Benard S. Mwankemwa,Setumo Victor Motloung,K.G. Tshabalala,R.O. Ocaya +5 more
TL;DR: In this article, the effect of annealing temperature (AT) on structure, morphology and optical properties of hydrothermally synthesized TiO2 nanocrystals was investigated. And the authors found that AT over the 200 to 600°C temperature range causes the band gap to decrease from 3.08 to 2.73
Journal ArticleDOI
Luminescence properties of Ce3+ and Tb3+ co-activated ZnAl2O4 phosphor
K.G. Tshabalala,So-Hye Cho,Jong Keuk Park,Shreyas S. Pitale,I.M. Nagpure,Robin E. Kroon,H.C. Swart,Odireleng M. Ntwaeaborwa +7 more
TL;DR: In this paper, a solution combustion method was used to prepare green emitting Ce 3+ -Tb 3+ co-activated ZnAl 2 O 4 phosphor, which was annealed at 700°C in air or hydrogen atmosphere to improve their crystallinity and optical properties.
