ER:YB:YAB CRYSTAL - AN OVERVIEW

The nonradiative transition rates follow the system WNR = W (0) exp(-alphap), the place 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 concept. In Tm3+ the temperature dependence of nonradiative peace rates is intricate b
