CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition costs Adhere to the system WNR = W (0) exp(-alphap), in which p is the number of phonons matching the Electricity gap. The nonradiative changeover charges of Er3+ show temperature dependence in step with the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative relaxation costs is complex because o
