The nonradiative transition fees Stick to the formula WNR = W (0) exp(-alphap), in which p is the volume of phonons matching the Power gap. The nonradiative changeover charges of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation concept. In Tm3+ the temperature dependence of nonradiative leisure rates is https://sybils147rqn8.wikiannouncing.com/user
