The nonradiative changeover fees Keep to the formula WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the energy gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace prices is sophisticated https://jonahd332tht7.prublogger.com/profile
