Photoluminescence, TGA/DSC and photocatalytic activity studies of Dy3+doped SrY2O4nanophosphors

Abstract

Dy3+:SrY2O4nanophosphors were preparedviaa solution combustion method using glycine as an organic fuel. The structural, optical, and thermal properties of the nanophosphors were studied. Strain and crystal size were calculatedviaW-H analysis. The direct energy band gap is nearly 4.9 eV and photocatalytic studies reveal that Rh-B degradation of almost 50% can be achieved.
