The nonradiative transition charges Adhere to the method WNR = W (0) exp(-alphap), where p is the amount of phonons matching the Electrical power gap. The nonradiative transition costs of Er3+ show temperature dependence in line with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices https://landenywqhm.shotblogs.com/er-yb-yab-crystal-an-overview-47166686
