The nonradiative changeover premiums Adhere to the formula WNR = W (0) exp(-alphap), exactly where p is the volume of phonons matching the Strength hole. The nonradiative transition prices of Er3+ exhibit temperature dependence according to the multiphonon relaxation idea. In Tm3+ the temperature dependence of nonradiative relaxation charges is https://erybyabcrystal17395.shotblogs.com/little-known-facts-about-er-yb-yab-crystal-47095271
