Abstract
Different concentrations of Eu3+ doped YPO4 samples were prepared using the co-precipitation reaction. The prepared samples were characterized by using XRD, PL (Photoluminescence), and FTIR. The crystallite sizes of the samples are found to be in the range of 10–18 nm. Photoluminescence studies give information about the excitation and emission spectra of the synthesized samples. Among the different concentrations of Eu3+ doped samples, 5at.% doped sample gives the highest emission spectrum as compared to others. Two intense emission peaks were found at 593 nm and 618 nm. These peaks are due to 5D0 -7F1 (magnetic dipole transition) and 5D0 - 7F2 (electric dipole transition) transitions of Eu3+ respectively. The average lifetime of the synthesized samples is found to be 3.52 ms.
