C ubic Y 2 O 3 :Eu 3+ 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 Y 3+ to Eu 3+ 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 with an average grain size of about 1 μm. The red phosphor exhibits strong red emission of the 5 D 0 → 7 F 2 transition for Eu 3+ at 611 nm, under 254 nm excitation. |
