FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative changeover premiums Adhere to the formula WNR = W (0) exp(-alphap), exactly where p is the quantity of phonons matching the Power gap. The nonradiative transition costs of Er3+ show temperature dependence according to the multiphonon rest idea. In Tm3+ the temperature dependence of nonradiative rest rates is complicated via the exi
