Role of Dysprosium in In 2-x Dy x O 3 to Enhance White Light Emission in OLED

OLED material is always having much science to explore in them. The role of rare earth Dy as a dopant material in well studied In2O3 is studied. The candidature of the white light emission from the Organic light emitting diode is explored in the present work. The doping concentration effect and the corresponding emission is shown in the present work. It is emphasized that the doping at nearly x = 1 mol% of dysprosium could alter the transition states and the output of the emission is pure white which is corresponds to the luminescence peaks. Color purity and co-related color temperature was calculated by CIE technique. The spectroscopic parameters are calculated by Judd-Oflet approaches which is suitable for RE3+ (RE= rare earth) ions. The present prepared phosphor is suitable for white light emission and used in display devices applications.
