The nonradiative changeover prices Adhere to the method WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Power gap. The nonradiative changeover prices of Er3+ show temperature dependence consistent with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated https://stevey468vus9.blog-mall.com/profile
