The nonradiative transition premiums follow the system WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative peace premiums is complex from the https://coletteh791bzw1.get-blogging.com/profile
