Abstract
ZrW2O8 nanorods doped with various concentrations of Dy3+ ions (5 - 15 mol%) showing excellent photoluminescence (PL) properties were synthesized by the facile hydrothermal method for white light applications. The products were comprehensively analyzed using a range of structural, morphological, and optical techniques. The optical studies were conducted by utilizing UV-visible and photoluminescence spectrophotometers. The photoluminescent emission spectra exhibit two prominent peaks at wavelengths of 479 nm and 572 nm, along with a less intense peak at 661 nm when subjected to excitations at wavelengths of 286 nm and 352 nm, and a highly dominating yellow emission with a faint red emission was obtained at 452 nm excitation. The almost constant value Y/B intensity ratios, lifetime values, CIE coordinates, and CCT values suggest that the obtained nanophosphor can be effectively employed in white light-emitting diodes (WLEDs) and various other lighting devices.
