Krishna, D. Haranath, S. Singh, Harish Chander, A. Pandey, D. Kanjilal] Zinc oxide doped with europium has been prepared by high temperature calcination method using ZnO, Eu2O3, and LiOH. Structural characterization by X-ray diffraction and optical studies by photoluminescence spectroscopy together give evidence that Eu3+ is going to the substitutional site of Zn2+. The concentration of chemicals used, sintering temperature, and time are optimized with photoluminescence excitation spectroscopy for a sharp and intense red signal which is a signature of Eu3+. Characteristic red emission at 607nm is observed using high-energy excitation along with the native deep center emission of ZnO peaking around 525nm.
