LITTLE KNOWN FACTS ABOUT ER:YB:YAB CRYSTAL.

The nonradiative transition costs Adhere to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative transition charges of Er3+ exhibit temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is difficult with t
