A fluorescent color wheel includes a substrate, a working fluid, and a fluorescent powder layer. The substrate has at least one flow channel therein. The flow channel has a first end and a second end respectively adjacent to a central region and a peripheral region of the substrate. The working fluid flows in the flow channel in a gas-liquid coexistence state. The fluorescent powder layer is disposed on the substrate and located at the peripheral region. The disclosure further discloses a projector adopting the fluorescent color wheel.
