发射能级 meaning in English
emission level
Examples
- It is found that the exciting spectra is moving to long wave with the increasing of eu concentration , emission intensity is rising , the properity of red homochromy is becoming better because of the different quench concentration of emission levels 5do , 5dj and 5d2 - when the concentration of eu is up to 1 . 2mol % , the emission levels 5di and 5d2 is quenching
研究发现，随着eu浓度的增加，荧光体y2o2s ： eu激发光谱发生红移，发射强度增大，红色单色性变好，这是因为eu的5d0和sdl 、 5d2发射能级跃迁发光的淬灭浓度不同，当浓度1 . 2mol时，后两者因交叉弛豫引起浓度淬灭。
