TOP GUIDELINES OF ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the method WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence in keeping with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest costs is intricate because of th
