摘要：
Layers of a passivating material and/or containing luminescent centers are deposited on phosphor particles or particles that contain a host material that is capable of capturing an excitation energy and transferring it to a luminescent center or layer. The layers are formed in an ALD process. The ALD process permits the formation of very thin layers. Coated phosphors have good resistance to ambient moisture and oxygen, and/or can be designed to emit a distribution of desired light wavelengths.
