CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative transition costs Keep to the formula WNR = W (0) exp(-alphap), wherever p is the amount of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ show temperature dependence per the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is sophisticated by th
