浓度猝灭 meaning in Chinese
concentration quenching
Examples
- The laser crystal also presents other attractive features , such as strong and broad absorption band , makes this laser medium to be an excellent candidate for efficient diode pumping without temperature controlling
该晶体可掺入较高浓度的yb离子( 0 . 5 ? 10 ) ，且不存在浓度猝灭。 - 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。 - By calculated judd - ofelt parameters of the npre - 1 glass and luminescence dynamics equation , the author has get the changing curve about light intensity near 1540nm with the increase of er doped concentration . it was observed that the light intensity is the strongest when er doped concentration is 20mol % and the concentration - quenching phenomenon takes place after the concentration is bigger than 20mol %
5 )通过建立发光动力学方程，利用j - o计算得到的参数，得出npre - 1样品1540nm处发光强度随er3 +离子掺杂浓度的变化规律，看到er3 +离子掺杂mol浓度为20 %时发光最强，大于这个浓度后就发生了浓度猝灭效应。
