Abstract
Provided is a fluorescent wheel for a projector capable of increasing the luminescence intensity and a light-emitting device for a projector using the same. The fluorescent wheel for a projector includes: an annular transparent substrate (11) including a first principal surface (11a) located on a side where excitation light (1) enters and a second principal surface (11b) located on a side where the excitation light (1) exits; a phosphor layer (12) provided on the second principal surface (11b) of the transparent substrate (11) and including an inorganic binder and a phosphor dispersed in the inorganic binder; and a filter layer (13) provided on the first principal surface (11a) of the transparent substrate (11) or between the second principal surface (11b) of the transparent substrate (11) and the phosphor layer (12) and configured to transmit the excitation light (1) and reflect fluorescence (2) emitted from the phosphor layer (12).
