Role of Dysprosium in In2-xDyxO3 to Enhance White Light Emission in OLED

Background: 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. Objective: The candidature of the white light emission from the Organic light emitting diode is explored in the present work. Methods: 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. Results: The spectroscopic parameters are calculated by Judd-Oflet approaches which is suitable for RE³⁺ (RE= rare earth) ions. Conclusion: The present prepared phosphor is suitable for white light emission and used in display devices applications.
