Photoluminescence, TGA/DSC and photocatalytic activity studies of Dy(3+) doped SrY(2)O(4) nanophosphors

Dy(3+):SrY(2)O(4) nanophosphors were prepared via a 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 calculated via W-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.
