LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

The nonradiative transition charges Stick to the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition costs of Er3+ show temperature dependence in step with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure fees is challenging
