摘要： Disclosed in the present disclosure are a new fluorescent powder capable of promoting plant growth under sunlight and preparation and use thereof. The fluorescent powder has a chemical formula of Sr4Al14O25: xMn4+, yMg2+, zLn3+. Compounds are weighed according to a stoichiometric ratio of various chemical components in the chemical formula; a fluxing agent is added and uniformly mixed; and a resulting mixture is calcined, naturally cooled to room temperature, and then ground to obtain the new fluorescent powder. The fluorescent powder has can emit red light that is conducive to plant growth, improves the utilization rate of sunlight, promotes plant growth, and is low in cost, high in efficiency, green and pollution-free.
