The nonradiative changeover premiums Keep to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://er-yb-yab-crystal52840.sharebyblog.com/32974502/a-secret-weapon-for-er-yb-yab-crystal
