Abstract

This document shows the desired format and appearance of a manuscript prepared for the Proceedings of the ICO20. It contains general formatting instructions and hints about how to use it. The (Y_0.99Nd_0.01)₃Al₅ O₁₂ nano-sized powders were synthesized by low temperature combustion (LCS), using Nd₂O₃, Y₂O₃, Al(NO₃) ₃♦9H₂O, ammonia water and citric acid as starting materials. This method effectively solves the problems caused by solid-state reaction at high temperature and hard agglomerates brought by chemical precipitation method. The powders were characterized by TG-DTA, XRD, TEM respectively. The study focused on the photoluminescence (PL) spectra of (Y_0.99Nd_0.01)₃Al₅ O₁₂ ceramic green and sintered disks. The experiments show that the forming temperature of YAG crystal phase is 850°C and YAP crystal phase appearing during the calcinations transforms to pure YAG at 1050°C. The particle size of the powders synthesized by the LCS is in range 20-50nm depending on the thermal treatment. The effectively induced cross section (σ_in) with the value 4.03×10^-19cm² of (Y_0.99Nd_0.01)₃Al₅ O₁₂ ceramics is about 44% higher than that of single crystal.
