波長域での吸収率が大きく異なる。The rare-earth oxide ultrafine particles of the present invention have a different reflection spectral distribution from the conventional rare-earth oxide fine particles having an average particle diameter of the order of several μm. As an example, Ho 2 average particle diameter used for the reflective spectral distribution and the present invention of Ho 2 O 3 fine particles of a conventional average particle diameter of about 2μm is 30nm
Comparing the reflection spectral distribution of the O 3 ultrafine particles, they have a major absorption peak in the wavelength range around 460 nm, 540 nm, and 650 nm regardless of the particle diameter.
