A SECRET WEAPON FOR ER:YB:YAB CRYSTAL

The nonradiative transition rates Adhere to 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 principle. In Tm3+ the temperature dependence of nonradiative leisure fees is chall
