The nonradiative transition charges follow the system WNR = W (0) exp(-alphap), wherever p is the number of phonons matching the Electricity hole. The nonradiative changeover prices of Er3+ exhibit temperature dependence in keeping with the multiphonon relaxation theory. In Tm3+ the temperature dependence of nonradiative rest charges is intricate https://mariozdbzx.review-blogger.com/54991337/details-fiction-and-er-yb-yab-crystal
