摘要：
The luminescence properties of some rare earch (Ln) ions adsorbed on Porous Vycor Glass (PVG) are studied. The results are used to characterize this system. Vibronic sidebands in the emission spectrum of Gd3+/PVG show that the Ln ions are bound to the surface of the pores of PVG and that they are coordinated on the other side by water molecules. From the decaytime of Eu3+ on PVG the number of coordinating water molecules is found to be 4 Energy transfer experiments show that the mean distance between two adsorbed Ln ions is about 7 angstrom.
