ER:YB:YAB CRYSTAL CAN BE FUN FOR ANYONE

The nonradiative transition prices Adhere to the system WNR = W (0) exp(-alphap), where by p is the quantity of phonons matching the Strength gap. The nonradiative changeover rates of Er3+ exhibit temperature dependence consistent with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative leisure premiums is difficul
