ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition premiums Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in step with the multiphonon rest concept. In Tm3+ the temperature dependence of nonradiative leisure rates is intricate by
