CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition costs Stick to the system WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Power hole. The nonradiative transition charges of Er3+ show temperature dependence in step with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure costs is complicated from the
