Solid-state lighting is widely utilized in various fields such as indoor and outdoor lighting, decorative lighting, automotive lighting, agricultural lighting, projection display and more due to its advantages of high efficiency, energy conservation, and environmental protection. However, high power and exceptional quality solid-state lighting technology put forward higher requirements for the service stability of fluorescent conversion materials. Fluorescent glass has emerged with its advantages of simple preparation process, low cost, and stable luminescence. Herein, the latest research progress in the preparation of fluorescent glass for solid-state lighting is reviewed. The preparation methods of fluorescent glass including one-step mixed sintering, two-step mixed sintering, twostep substrate forming sintering, spark plasma sintering, microwave sintering, Joule heating, induction heating and laser sintering are systematically summarized. The technical difficulties, spectral regulation strategy and device application of different preparation methods are analyzed. Finally, the problems of fluorescent glass preparation, functional structure design and device packaging are discussed, and the research trend of fluorescent glass preparation for solid-state lighting is prospected.
