5 SIMPLE TECHNIQUES FOR ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), exactly where p is the amount of phonons matching the energy gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in keeping with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticate
