NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Vitality hole. The nonradiative changeover premiums of Er3+ show temperature dependence in keeping with the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace charges is intricate fr
