Study on VUV and UV Excitation Spectrum of GdVO4∶Eu3+

The photoluminescence spectra and excitation spectra in the vacuum ultraviolet (VUV) and ultraviolet (UV) spectra region of GdVO4∶Eu3+ were reported. The excitation and emission spectra indicate that GdVO4∶Eu3+ is a highly efficient phosphor for the excitation in the VUV and UV spectrum region. The excitation band in the VUV and UV spectrum region of 60～350 nm consists mainly of the absorption of host, which has obvious absorption of 4fn-15d of Eu3+ and Gd3+. In GdVO4∶Eu3+, there is the energy transfer： VO43-→Eu3+, Gd3+→Eu3+ and Gd3+→VO43-→Eu3+. Through the last two procedures, maybe the quantum cutting of Gd3+-Eu3+ occurs.
