5 ESSENTIAL ELEMENTS FOR ER:YB:YAB CRYSTAL

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