The nonradiative transition premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electricity gap. The nonradiative transition fees of Er3+ exhibit temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated https://er-yb-yab-crystal72615.ssnblog.com/32248331/examine-this-report-on-er-yb-yab-crystal
