Abstract
An inorganic fluorescent material for solid-state light source is associated with a GaInN heterojunction blue solid-state light source to form a white light source. The fluorescent material is represented by the general formula of (Y,Gd,Dy,Yb,Er,Ce)(Al,Ga,Sc,In)O, wherein α is in the range of 2.97–3.02, β is in the range of 4.98–5.02, x is in the range of 0.2–0.65, y is in the range of 0.001–0.05, z is in the range of 0.01–0.05, q is in the range of 0.001–0.05, p is in the range of 0.015–0.1, k is in the range of 0.01–0.6, n is in the range of 0.01–0.45, and l is in the range of 0.01–0.1. The short-wavelength light emitted from the GaInN heterojunction blue solid-state light source is mixed with a wide-bandwidth light emitted from the fluorescent material to generate a mixed light of a wavelength of about 535 nm–590 nm.
