Plant laser lighting fluorescent glass-ceramics is composed of 5-30wt% of red fluorescent powder and the balance of a glass matrix; the red fluorescent powder emits 660nm wide spectrum deep red light under excitation of a blue laser light source, the full width at half maximum is wider than 60nm; and red fluorescent powder crystalline grains are uniformly embedded in the glass matrix. The advantages of the plant laser lighting fluorescent glass-ceramics are that: the fluorescent glass-ceramics emits high brightness 660nm wide spectrum red light under excitation of a blue semiconductor laser, partly-transmitted-out blue laser and the red light emitted by the fluorescent glass-ceramics are matched with effective spectrum of plant photosynthesis, at the same time, the plant laser lighting fluorescent glass-ceramics can obtain a high brightness plant laser lighting source under excitation of high energy density laser, and has potential application in the fields such as a plant factory, vertical planting, a greenhouse, a glass cultivation room, and the like.
