Abstract

See full text

Fluorescent material composite particles include translucent inorganic particles having a volume average particle diameter in a range of 30 nm or more and 500 nm or less, fluorescent nanoparticles having an average particle diameter in a range of 5 nm or more and 25 nm or less, and a first resin. At least a part of each of the translucent inorganic particles are embedded in the first resin. The translucent inorganic particles are unevenly distributed to a surface of the fluorescent material composite particles. The fluorescent material composite particles have a volume average particle diameter in a range of 0.5 μm or more and 50 μm or less.
