CONSIDERATIONS TO KNOW ABOUT ER:YB:YAB CRYSTAL

The nonradiative changeover charges Stick to the system WNR = W (0) exp(-alphap), the place p is the amount of phonons matching the Electricity gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence according to the multiphonon rest principle. In Tm3+ the temperature dependence of nonradiative peace rates is intricate with the
