摘要： Disclosed are rare earth phosphate particles that include aggregated particles formed of a plurality of primary particles of a rare earth phosphate represented by LnPO4, wherein Ln represents at least one element selected from the group consisting of Sc, Y, La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy, Ho, Er, Yb, and Lu. The cumulative volume particle size at a cumulative volume of 50 vol %, D50, of the aggregated particles is from 0.1 μm to 20 μm as measured through particle size distribution analysis using a laser diffraction and scattering method. The rare earth phosphate particles are to be distributed in a substrate or on a surface of a substrate and used to cause scattering of light.

摘要： Provided are: a pyrrolidine derivative containing quaternary ammonium cations having a bicyclo framework that can be used as an organic structure directing agent; a method for producing the same; an MSE-type zeolite; and a method for producing the same.
The pyrrolidine derivative containing quaternary ammonium cations having a bicyclo framework has, in an X-ray diffraction spectrum, a highest peak intensity I in a diffraction angle (2θ) range of 14.0° to 16.0° and a highest peak intensity II in a diffraction angle (2θ) range of 17.0° to 19.0°, wherein a peak intensity ratio (I/II) of the peak intensity I to the peak intensity II is in a range of 0.4 or more and 1.5 or less.
