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.

A printing system is disclosed. The printing system includes a first printer to print a first type of data to a medium and to print a barcode on the medium including variable data to be printed on the medium and a second printer to print the variable data to the medium based on the barcode. The second printer includes a barcode reader, transfer location and a medium path having a fixed distance between the barcode reader and the transfer location.
