Abstract:
A light emitting device includes a light emitting element of a peak emission wavelength in a range of 430 nm to 470 nm and a fluorescent member. The fluorescent member includes a first phosphor including a silicate having a composition that contains at least one element selected from the group consisting of Ca, Sr, and Ba, at least one element selected from the group consisting of Cl, F, and Br, and Mg and Eu, a second phosphor including an aluminate that has a composition containing Lu and Ce, and a third phosphor having emission spectrum with a half bandwidth of 86 nm or less and including a silicon nitride that has a composition containing at least one of Sr or Ca, and containing Al and Eu.
