模块式荧光光谱仪-Fluorolog-3对纯态氧的测量

A Fluorolog® spectrofluorometer, equipped with a 450-W xenon lamp, single-grating monochromators, and near-IR accessories (DSS-IGA020L InGaAs detector and emission grating at 600 grooves mm , blaze = 1000 nm) was used to measure the 1O2 emission spectrum. A high-pass filter (λ = 780 nm) acted as an order-sorter, necessary when such large wavelength-ranges are spanned. Fig. 1 shows the emission spectrum with an integration time of 0.1 s and a bandpass of 12 nm. Note the excellent signal-to-noise ratio.
