FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative changeover charges follow the components WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electrical power hole. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative relaxation premiums is dif
