The nonradiative changeover costs Stick to the formula WNR = W (0) exp(-alphap), where p is the volume of phonons matching the Electricity gap. The nonradiative transition prices of Er3+ show temperature dependence consistent with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative leisure charges is difficult https://paxtonlonlh.bluxeblog.com/65370415/the-definitive-guide-to-er-yb-yab-crystal
