A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the Electricity hole. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative relaxation rates is complicated thr
