Light-emitting device and electronic apparatus

A light emitting device, comprising:

• a solid-state light-emitting element that emits primary light;
• a wavelength converter that includes a phosphor containing a fluorescent ion which absorbs the primary light on the basis of a forbidden transition-type electronic energy transition;
• and
• an optical member that reflects the primary light while transmitting fluorescence emitted by the fluorescent ion;
• wherein
• the solid-state light-emitting element is arranged on a side of one surface of the wavelength converter and the optical member is arranged on a side of the other surface of the wavelength converter,
• the fluorescence emitted by the fluorescent ion passes through the optical member and is output to the outside,
• the wavelength converter absorbs the primary light emitted by the solid-state light-emitting element and converts it into a first fluorescence having a longer wavelength than that of the primary light, and absorbs the primary light reflected by the optical member and converts it into a second fluorescence having a longer wavelength than that of the primary light, and
• the first fluorescence and the second fluorescence have a fluorescence peak within a wavelength range of 700 nm to 2500 nm.
