摘 要：The synthesis, composition optimization, VUV Photoluminescence （PL） spectra, and optical properties, of （Y,Gd）（V,P）O4∶Eu3+ phosphors were investigated by synchrotron radiation. The VUV PLE spectra and the correlation among VUV PL intensity, λem, and Eu3+, Gd3+, and P-content were established. The PLE spectral studies showed that （Y,Gd）（V,P）O4∶Eu3+ exhibited significant absorption in the VUV range. The VUV PL intensity was found to enhance with PO43- and Gd3+-doping. Furthermore, the chromaticity characteristics of （Y,Gd）（V,P）O4∶Eu3+ were also found to be （0.6614, 0.3286） and compared against （Y, Gd）BO3∶Eu3+ as a reference. Based on the characterization results, we are currently improving and evaluating the potential application of （Y,Gd）（V,P）O4∶Eu3+ as a new red-emitting PDP phosphor.
