observed concentrations meaning in Chinese

观察到的浓度

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。
