Abstract
The absolute fluorescent quantum efficiencies of NBS phosphor standard samples which were excited by a 254nm radiation were measured by a polychromator. The polychromator was calibrated by a conical cavity thermal radiation detector, which used polyvinylidene fluoride (PVDF) films, coated inside with gold black absorber. The effective spectral absorptance of the derector was constant within 0.3% over a wavelength region of 200-600nm. Reproducibility of the absolute fluorescent quantum efficiency was within ±0.02.<BR>The relative values of fluorescent quantum emitted per 254nm incident radiation quantum agreed with the NBS data within 3%. The fluorescent quantum efficiency of NBS phosphor standard samples (NBS 1027) was 0.81.
