使用波长为808urn的红9呼导体激光以及波长为658urn的染料激光分别共振激发接饵机酸包(Er‘+NV04)中Er’十离子的‘I。l。和‘F。l。态探测到对应跃迁‘易/。、‘八。l。和‘凡l。、‘入。l。的波长在55311和41011附近的上转换荧光。在染料激光激发下测量了不同Er’十浓度
The Er ’decay ion’ I in the bait machine acid bag (Er ’+ NV04) is excited by the red 8-wavelength laser with a wavelength of 808urn and the dye laser with a wavelength of 658urn. l. And ’F. l. State detected the corresponding transition ’easy /. ,’Eight. l. And ’Where l. , ’Into. l. Upconversion fluorescence at wavelengths around 55311 and 41011. Different Er ’concentrations were measured under dye laser excitation
