TEMPERATURE-DEPENDENT ENERGY TRANSFER FROM 5D 3 AND 5D4 STATES OF TB3 + TO SM3 + .

Article abstract of DOI:10.1016/0022-3697(88)90067-4

The present study deals with the interaction of **5D//3 and **5D//4 states of Tb**3** plus when Sm **3** plus ions are incorporated in a LaCl//3 matrix. A dipole-dipole interaction mechanism is suggested for the transfer of energy from **5D//3 and **5D//4 states of Tb**3** plus to Sm**3** plus . Temperature-dependent study reveals multiphonon relaxation of the LaCl//3 matrix.
