NOT KNOWN FACTUAL STATEMENTS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticated through th
