The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), where by p is the amount of phonons matching the Electrical power hole. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is intricate
