The nonradiative changeover premiums Stick to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest premiums is https://erybyabcrystal06284.oblogation.com/32355464/5-easy-facts-about-er-yb-yab-crystal-described
