Lumino-structural properties of Dy activated NaBaLaNbO phosphors with enhanced internal quantum yield for w-LEDs.

With an intend to develop white light emitting phosphor, for w-LED application, a series of dysprosium (Dy) doped novel NaBaLaNbO phosphors were prepared using solid state reaction technique at 1300 °C. Their structural, morphological and vibrational spectroscopic analysis was performed. We illustrate the luminescence characteristics of the prepared phosphors for various Dy ion doping concentration.
