Green Route Synthesis, Structural and Luminescence Studies of Mg-Doped Y₂O₃ Nnanophosphor

Abstract:

We report the synthesis of Y₂O₃:Mg²⁺ (0.5-9mol %) nanoparticles (NPs) with different morphologies via ecofriendly, inexpensive and simple low temperature solution combustion method using Aloe Vera gel as fuel. The formation of different morphologies was characterized by PXRD, SEM, UV-Visible, PL techniques etc. The PXRD data confirms the formation of single phase Y₂O₃ with cubic crystal structure. The influence of Mg ions concentration on the morphology, UV absorption and PL emission were investigated in detail. NPs exhibit white light emission with CIE chromaticity coordinates (0.317, 0.32 and 0.308, 0.359) and correlated color temperature values 6298 and 6674 respectively. These findings show a great promise of Y₂O₃: Mg²⁺ NPs as a phosphor in warm white LEDs.
