FACTS ABOUT ER:YB:YAB CRYSTAL REVEALED

The nonradiative transition rates Keep to the formula WNR = W (0) exp(-alphap), the place p is the volume of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence according to the multiphonon leisure theory. In Tm3+ the temperature dependence of nonradiative peace rates is intricate w
