The nonradiative transition costs follow the system WNR = W (0) exp(-alphap), where p is the quantity of phonons matching the Electrical power gap. The nonradiative transition premiums of Er3+ exhibit temperature dependence per the multiphonon peace theory. In Tm3+ the temperature dependence of nonradiative leisure charges is difficult through https://dallaseiigc.ampedpages.com/top-latest-five-er-yb-yab-crystal-urban-news-61707214
