NOT KNOWN DETAILS ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover costs Stick to the formula WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Power hole. The nonradiative changeover prices of Er3+ show temperature dependence in line with the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative rest rates is sophisticated with the ex
