    摘要： β-Sialon comprising Eu2+ that is present in a solid solution form in β-sialon represented by Si6-zAlzOzN μm [wherein z is 0.3-1.5], which shows, when excited with light of 450 nm in wavelength, a peak wavelength of fluorescent spectrum of 545-560 nm, a half-value breadth of 55 nm or greater, and an external quantum efficiency of 45% or greater. The β-sialon can be produced by blending at least one kind of oxide selected from aluminum oxide and silicon oxide with silicon nitride and aluminum nitride in such a manner as to give z of 0.3-1.5, further adding thereto a europium compound and a β-sialon powder having an average particle diameter of 5 μm or greater and an average degree of circularity of 0.7 or greater, each in a definite amount, and baking the mixture.

    摘要： A particulate matter concentration measuring apparatus configured to measure a particulate matter concentration in exhaust gas includes an exhaust gas extraction line that is branched from an exhaust line and has a flow passage cross-sectional area smaller than that of the exhaust line, a particulate matter detection filter provided in the exhaust gas extraction line and configured to catch particulate matter, a heating unit configured to heat the caught particulate matter, and a differential pressure detection unit configured to detect a differential pressure generated between an inlet and an outlet of the particulate matter detection filter. The heating unit is configured to apply about 50% or more of a calorific value for heating the particulate matter to an area making up about 30% of the particulate matter detection filter on an upstream side of an exhaust gas flow.
