The nonradiative changeover rates Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition fees of Er3+ exhibit temperature dependence per the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative peace charges is sophisticated https://erybyabcrystal29516.bluxeblog.com/65195527/top-guidelines-of-er-yb-yab-crystal
