Abstract: SiO2@SrTiO3:Eu3+ (1 mol%), Li (1 wt%) core–shell nanopowders (NPs) were prepared by using combustion process and its morphology was studied. SiO2@SrTiO3: Dy3+ (5 mol %) nanopowders fabricated via the low temperature sonochemical route by utilizing bio-surfactant Aloe Vera gel extract. SEM analysis was done. Broom-like hierarchical structures of SrTiO3:Nd3+ (1–11 mol %) nanophosphors (NPs) were fabricated via CTAB assisted hydrothermal route. Controlled experiments namely, reaction temperature, surfactant concentration, pH and time duration were performed and its influences on morphology of the product was investigated. These conditions may tune the simple structures to broom-like hierarchical structures.

Keywords: Bio- surfactant, Core-shell, Alkali – halide fluxes, Nanophosphor
