Abstract
Energy transfer in LaF3; Er, Yb is studied by observing the lifetimes of Er3+ in excited states and the excitation spectra both at room temperature and at 77 °K. It is found that the energy transfer from Er3+ (4 S 3/2→4 I 13/2) to Yb3+ (2 F 7/2→2 F 5/2) is associated with the emission of three phonons of about 350 cm−1, and that the energy transfer from Er3+ (2 H 9/2→4 F 9/2) to Yb3+ accompanied by the absorption of phonons takes place.This publication has 7 references indexed in Scilit:
