Abstract
A core-shell fluorescent material and a light source device using the same are disclosed. The core-shell fluorescent material includes a core and a shell for generating an emitting light with wavelength within 520 and 800 nm after absorbing an exciting light with wavelength within 370 and 500 nm. The core may include yellow, green or red fluorescent powder, and the shell includes manganese (IV)-doped fluoride compound. The light source device generally includes the core-shell fluorescent material, a radiation source, leads and a package. The leads provide current to the radiation source and cause the radiation source to emit radiation. The core-shell fluorescent material is coated on the package for receiving the radiation so as to generate a high quality emission served as the desired light source for the field of lighting and displaying.
