CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Electricity hole. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon rest theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is intricate f
