LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

The nonradiative transition costs Stick to the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity hole. The nonradiative changeover fees of Er3+ exhibit temperature dependence consistent with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex t
