THE BASIC PRINCIPLES OF ER:YB:YAB CRYSTAL

The nonradiative transition charges Stick to the formula WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Strength hole. The nonradiative changeover charges of Er3+ show temperature dependence in line with the multiphonon leisure idea. In Tm3+ the temperature dependence of nonradiative peace prices is intricate by the exis
