β¦ Synopsis
The Iuminescence spectra of Bi 3+incorporated in yttrium &nnmnm borate are reported_ At liquid hehum temperature the emission band shows vibrational structure with equidistant lines. The efficiency of energy transfer from Bi3* to Tb3+ and from Ce3+ to Tb3*has also been measured. The energy transfer from Bi3* to lb 3* is more efficient than that from Ce3' to Tb3*_

The luminescence intensity of Bi 3+ in Y203 decreases not only on increasing but also on decreasing the temperature. An explanation is proposed and the nature of the nonradiative process is discussed. Data on Bi3+-activated Lu203 and La203 are also reported.
