Microstructural and photoluminescence properties of sol–gel derived Tb3+ doped ZnO nanocrystals

Author: Kabongo, GL ; Mhlongo, Gugu H ; Malwela, T ; Mothudi, BM ; Hillie, KT ; Dhlamini, MS Date: Apr 2014 Un-doped and Tb(Sup3+) doped ZnO nanocrystals with different concentrations of Tb(Sup3+) were synthesized by a sol–gel method and their photoluminescence (PL) properties were investigated. The successful incorporation of Tb(sup3+) ions with ... Read more
Sensitizing effects of ZnO quantum dots on red-emitting Pr3+-doped SiO2 phosphor

Author: Mbule, PS ; Mhlongo, Gugu H ; Pitale, SS ; Swart, HC ; Ntwaeaborwa, OM Date: May 2012 In this study, red cathodoluminescence (CL) ( emission=614 nm) was observed from Pr3+ ions in a glassy (amorphous) SiO2 host. This emission was enhanced considerably when ZnO quantum dots (QDs) were incorporated in the SiO2:Pr3+ suggesting ... Read more
Synthesis and characterisation of quantum dots coupled to mycolic acids as a water-soluble fluorescent probe for potential lateral flow detection of antibodies and diagnosis of tuberculosis

Author: Kabwe, KP ; Nsibande, SA ; Lemmer, Yolandy ; Pilcher, LA ; Forbes, PBC Date: Nov 2021 This work explores the potential use of cadmium-based quantum dots (QDs) coupled to mycolic acids (MAs) as a fluorescent probe to detect anti-MA antibodies which are biomarkers for tuberculosis (TB). The use of free MAs as antigens for the ... Read more
