Light-emitting device

A light-emitting device, comprising

• a light-emitting element that has a dominant wavelength in a range of 380 nm or more and 485 nm or less, and
• a fluorescent material layer that comprises a fluorescent material emitting light by being excited by light emitted from the light-emitting element, and a neodymium compound,
• the light-emitting device emitting light having a dominant wavelength in a range of 584 nm or more and 780 nm or less, and exhibiting a yellowish-red light emission color to red light emission color,
• wherein the light-emitting device has a half value width in a light emission spectrum in a wavelength range of 584 nm or more and 780 nm or less being in a range of 50 nm or more and 100 nm or less,
• wherein the fluorescent material comprises at least one nitride fluorescent material selected from the group consisting of a first nitride fluorescent material having a composition represented by the following formula (1), and a second nitride fluorescent material having a composition represented by the following formula (2):
• (Ca,Sr)AlSiN3:Eu (1)
• (Ca,Sr,Ba)2Si5N8:Eu (2)
• wherein the fluorescent material layer has a content of the neodymium compound in a range of 5 parts by mass or more and 40 parts by mass or less relative to 100 parts by mass of the fluorescent material.
