FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition prices follow the components WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electrical power gap. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex be
