Low-temperature synthesis and particle size effect on photoluminescence of YVO4:Eu nanocrystals
Source abstract
Abstract
Strong-luminescence YVO4:Eu nanoparticles were prepared by wet chemical reaction at 155°C. Energy transfer processes from V–O and Eu–O to Eu3+ and f–f transition of Eu3+ are identified. Luminescence intensity is highest when excited through V–O charge transfer band. Also, luminescence intensity increases with heat treatment temperature up to 900°C due to increase of radiative rate. The luminescence emission intensity could be improved after covering the nanoparticles with an undoped shell. Bi-exponential decay is found.
