Abstract:
A wavelength-converting film includes a sintered body formed of a mixture of a wavelength-converting material and a glass composition. The wavelength-converting material includes a quantum dot having a core-shell structure and a protective layer coating a surface of the quantum dot. A shell of the quantum dot contains at least one of Zn, S, and Se, the protective layer does not contain S and Se, and the glass composition includes a SnO2—P2O5—SiO2-based composition.
