| Abstract: | Bundle-like YPO4/Eu3+ microarchitectures were successfully synthesized from starting materials Y(NO3)3,Eu(NO3)3 and(NH4)2HPO4 by a urea-assisted hydrothermal method in the presence of urea as an auxiliary agent.The crystal structure,morphology and luminescent properties of the product were analyzed by means of X-ray powder diffraction,transmission electron microscopy and photoluminescence spectrometry.The formation mechanism of YPO4/Eu3+ bundle-like architecture was proposed based on transmission electron m... |
