Planar laser induced fluorescence PLIFNO fluorspar spectrum adjustment.In recent years, including A2X (0, 0) with transition, NO spectral characteristics have been detailed discussion [10], encouraging the line part wavelength and spectral characteristic coefficient can be very convenient, is, here for NO fluorescence spectrum feature does not make specific comments debate, just let's do some test result to clarify.Figure 2 (a), (b) are NO fluorescent lights with flags, the spectra in the middle of the wavelength is 240 nm, the wavelength of laser encourage line is about 226.61 nm.Two pictures in addition to the Rayleigh scattering spectrum of a standard lamp (226 nm), also contains from energy state A2 Σ + argument on 'state X2 = 0 to next Π argument' = 0 (226 nm), argument "= 1 (236 nm), argument" = 2 (247 nm), argument "= 3 (258 nm) transition.Figure 2 (a) of methane in the atmosphere of flame 2 NO fluorescent lights with flags, figure 2 (b) to a high energy combustion agent dies NO fluorescent lights with flags, because 2 atmosphere of methane flame inside the NO content rarely, based on the fluorescent with led weak anomaly, figure 2 (b) the stronger fluorescence standard lights annotate the combustion agent dies NO member of a crowd of the weaker Rayleigh standard lamp, also illuminates the resonance abnormal receiving the attenuation of laser energy significantly and the resonance fluorescence standard leds is greater than the resonance fluorescence characteristic of a standard lights.Our company's main equipment and technology has the schlieren apparatus, photonic doppler velocimeter, planar laser induced fluorescence PLIF, etc.If there is any need to please contact us: 0816-6204826 |
