Abstract
A light emitting device generates a broadband light beam in response to an excitation light beam. The light emitting device includes a matrix in which is provided a plurality of fluorescent components of different types. Each type of fluorescent component has an absorption spectrum and an emission spectrum respectively differing from absorption and emission spectra of other types of fluorescent components. The matrix and the types, concentration and positioning of the fluorescent components are selected to output the broadband light beam in response to the excitation light beam. The types of fluorescent components may include fluorescent compounds, quantum dots or a combination thereof. The light-emitting device above may be used as a fluorescent standard, or incorporated into a light source. Scattering elements may also be incorporated in the matrix.
