ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition costs Stick to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative peace rates is intrica
