发光二极管(LED)因其快速提高的效率、耐用性和可靠性、在各种尺寸的产品中的可用性以及其环保成分而成为普通照明的优秀候选者。通过将一种或多种荧光粉材料与芯片相结合，可以实现有效的照明设备。因此，发展荧光粉的结构是非常重要的。尽管在过去的几年里已经提出了许多荧光粉，但适用于LED的荧光粉的范围有限。这项工作描述了我们在理解这类荧光粉的配方、形态、结构、光谱和包装方面的最新进展。它提出了进一步发展的途径和在荧光粉可以实际应用于LED之前必须克服的科学挑战。
Light-emitting diodes (LEDs) are excellent candidates for general lighting because of their rapidly improving efficiency, durability, and reliability, their usability in products of various sizes, and their environmentally friendly constituents. Effective lighting devices can be realized by combining one or more phosphor materials with chips. Accordingly, it is very important that the architecture of phosphors be developed. Although numerous phosphors have been proposed in the past several years, the range of phosphors that are suitable for LEDs is limited. This work describes recent progress in our understanding of the prescription, morphology, structure, spectrum, and packaging of such phosphors. It suggests avenues for further development and the scientific challenges that must be overcome before phosphors can be practically applied in LEDs.
