Photoluminescence of _Y2O₃:Eu³⁺ Prepared by the Wood Template

Abstract:

Cubic Y2O3:Eu3+ was successfully prepared by mimicking wood tissue of Nepal Alder. Its structure was characterized by X-ray diffraction pattern (XRD) and Energy dispersive X-ray spectroscopy (EDX). The results show that the sample shares the single phase of cubic structure. The composition analysis shows an approximate Y3+ to Eu3+ atom ratio of about 10:1. The scanning electron microscopy (SEM) images confirm that the sample shares the same shape as the wood tissue of Nepal Alder, which was composed of some thin fibers. The red phosphor exhibits strong red emission of the 5D0 → 7F2 transition for Eu3+ at 611 nm, under 254 nm excitation
