With the advantages of high brightness and long transmission distance, semiconductor laser is especially suitable for special lighting fields (such as laser car lights, projection display). In this review, the realization methods of laser lighting and its main problems are briefly discussed. The research progress of rare earth, semiconductor, and carbon dots fluorescent material in laser lighting is emphatically summarized. As the most commonly used fluorescent material for laser illumination at present, rare earth fluorescent materials mainly include rare earth phosphors, fluorescent ceramic, and fluorescent glasses, which have high photo-thermal stability. But their further application is restricted because of their non-renewable resources and high price. Semiconductor fluorescent materials mainly include the second-generation semiconductor quantum dot materials represented by CdSe and ZnS, the third-generation semiconductor materials represented by SiC and AlN, and perovskite materials. The second-generation semiconductor quantum dot materials and third-generation semiconductor materials have the advantages of high luminous efficiency and stable performance, but are limited by their cost and process. Perovskite materials exhibit adjustable band gap and stable spontaneous radiation, however, they contain toxic elements and are highly sensitive to the environment resulting in poor stability. Carbon dots phosphors with tunable emission wavelength and low toxicity, are mainly in two forms of light conversion materials and gain media, nevertheless, their thermal stability under laser is poor. At last, the development of fluorescent materials for laser lighting in the future is prospected.
