Particle mixture, method for improving light scattering property using the same, and light scattering member and optical device including the same

摘要

The particle mixture contains the following particles A and the following particles B, which are particles different from the particles A. [Particle A] Rare earth phosphate particles represented by LnPO ₄ (Ln is a rare earth element, and represents at least one element selected from the group consisting of Sc, Y, La, Eu, Gd, Dy, Yb, and Lu). [Particle B] Rare earth phosphate particles or rare earth titanium represented by LnPO ₄ (Ln is a rare earth element and represents at least one element selected from the group consisting of Sc, Y, La, Eu, Gd, Dy, Yb and Lu.) Salt particles.
