摘要：

The luminescence of potassium rare earth orthophosphates, K3RE(PO4)2, RE = La, Ce, Tb, was studied at 298 and 10 K under UV and VUV excitation. The band gaps determined by reflection and excitation spectra were found in the range 7.2-7.8 eV. The results are discussed. The observed narrow excitation band at the VUV absorption edge is caused by an excitation of PO43- anion molecules in the hosts.
