The nonradiative changeover charges follow the formula WNR = W (0) exp(-alphap), wherever p is the volume of phonons matching the Electrical power gap. The nonradiative changeover fees of Er3+ exhibit temperature dependence in line with the multiphonon relaxation principle. In Tm3+ the temperature dependence of nonradiative rest rates is https://er-yb-yab-crystal52840.blog-gold.com/41731470/what-does-er-yb-yab-crystal-mean
