The nonradiative transition premiums Stick to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength gap. The nonradiative changeover costs of Er3+ show temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative rest rates is complex https://jaroslave702dyu1.blog-gold.com/profile
