WHAT DOES ER:YB:YAB CRYSTAL MEAN?

The nonradiative transition premiums Keep to the method WNR = W (0) exp(-alphap), the place p is the number of phonons matching the Electricity gap. The nonradiative transition charges of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative peace premiums is intricate through the e
