Abstract

YPO4 nano/microparticles doped with Eu3+ (5 at. %) have been synthesized by hydrothermal route inducing organic additives citrite/oxalate, which acts as capping agent. It has been found that the varying the concentration of organic additives ions induces YPO4:Eu3+ a phase transformation from tetragonal to hexagonal, and also a significant decrease in Eu3+ luminescence intensity was observed. This is related to the association of the water molecules in the hexagonal phase of YPO4. The luminescent properties of YPO4:Eu3+ prepared with different organic additives-induced have been compared. The ratio of the intensity of electronic dipole transition 5D0-7F2 to the magnetic dipole transition 5D0-7F1 for hexagonal YPO4:Eu3+ prepared with oxalate-introduce is higher than that prepared with citrate-introduce..
