Abstract:
A wavelength conversion element includes a phosphor layer including phosphor particles configured to be excited by light from a light source and a matrix located among the phosphor particles; and a column-shaped structural body including at least two kinds of column-shaped bodies periodically arranged and in contact with the phosphor layer. The column-shaped bodies have different heights and/or different thicknesses. The column-shaped structural body is a photonic crystal.
