The advent of greenhouses greatly promoted the development of modern agriculture, which freed plants from regional and seasonal constraints. In plant growth, light plays a key role in plant photosynthesis. The photosynthesis of plants can selectively absorb light, and different light wavelengths result in different plant growth reactions. Currently, light-conversion films and plant-growth LEDs have become two effective ways to improve the efficiency of plant photosynthesis, among which phosphors are the most critical materials. This review begins with a brief introduction of the effects of light on plant growth and the various techniques for promoting plant growth. Next, we review the up-to-date development of phosphors for plant growth and discussed the luminescence centers commonly used in blue, red and far-red phosphors, as well as their photophysical properties. Then, we summarize the advantages of red and blue composite phosphors and their designing strategies. Finally, we describe several strategies for regulating the spectral position of phosphors, broadening the emission spectrum, and improving quantum efficiency and thermal stability. This review may offer a good reference for researchers improving phosphors to become more suitable for plant growth.
温室的出现极大地推动了现代农业的发展，使植物摆脱了地域和季节的限制。在植物生长过程中，光照对植物光合作用起着关键作用。植物的光合作用能够选择性地吸收光，不同的光波长会导致不同的植物生长反应。目前，光转换薄膜和植物生长发光二极管已成为提高植物光合作用效率的两种有效方式，其中荧光粉是最关键的材料。本文首先简要介绍光对植物生长的影响以及促进植物生长的各种技术。接下来，我们综述了用于植物生长的荧光粉的最新进展，并讨论了蓝色、红色和远红色荧光粉中常用的发光中心及其光物理性质。然后，我们总结了红色和蓝色复合荧光粉的优势及其设计策略。最后，我们描述了几种调节荧光光谱位置、拓宽发射光谱以及提高量子效率和热稳定性的策略。这篇综述可为研究人员改进荧光粉以使其更适合植物生长提供良好的参考。
