concentration quenching meaning in Chinese

浓度猝灭
浓缩猝灭

Under 970nm - wavelength laser diode pumped , high efficient upconversion fluorescence near 480nm has been attained . from the comparison among luminescence intensity in samples with several different concentration , we can observe concentration quenching feature in these glasses . then we analyzed the reason on concentration - quenching which could be attributed to cross - relaxation mechanism
通过对不同掺杂浓度样品的发光比较，发现了这种玻璃上转换发光的浓度猝灭现象，找出了这种玻璃得到高效率上转换发光的适宜浓度，并对tm3 +的浓度猝灭现象进行了分析。
At the same time , we show that under a proper nitrogen doping concentration , due to the " concentration quenching " effect , the full spectrum of the nn3 center ( i . e . , its zero phonon line and various phonon replicas ) is revealed without the interference from the spectra of other higher energy centers ( especially nn4 - nn6 )
Gapi . xn :的发光谱在低组分下由尖锐的nn 。线及其声子伴线组成，随着组分x的提高，这些尖锐的的谱线逐渐展宽，并向低能端移动，在这个过程中，激子的能量传输起着重要作用
