The 5D3–5D4 cross relaxation process of Tb3+ in CsCdBr3 has been evaluated by analysis of the decay curves of the 5D3 and 5D4 emission. The temperature dependence of the cross relaxation rate can be explained assuming phonon-assisted processes. The results show that the larger amount of Tb3+ ions is incorporated in pairs into the CsCdBr3 lattice.
