摘要：
The emission and excitation spectra of Gd2SiO5 : Eu3+ were investigated using the VUV beam line of the Beijing Synchrotron Radiation Facility (BSRF). The experimental results were discussed in the frame of visible quantum cutting process involved in Gd3+ -Eu3+ system. Upon direct excitation into the (6)G(J) states of Gd3+, two visible photon emissions from Eu3+ were observed. Cursory evaluation proved that Gd2SiO5 : Eu3+ is an efficient visible quantum cutter.
