N2 - Borate, phosphate and tungstate glasses doped by Gd3+, Tb3+ and Eu3+ were excited by cathode rays. As a result of this, fluorescence identical with the fluorescence of glasses excited by optical means, was observed. In the Tb3+ doped glasses strong fluorescence from 5D3 level was obtained. This fluorescence was not observed under optical excitation with the Tb3+ concentration studied. The absence of quenching of the 5D3 level is discussed. It is proposed that cathode ray excitation can be used as an instrument for studying surface fluoresence in glasses.
