The nonradiative transition premiums Stick to the system WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Strength hole. The nonradiative transition rates of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates https://billyk812gec3.blogdal.com/profile
