Abstract

We have developed a process for coating individual phosphor particles with different coating compositions. The phosphor is suspended in a solvent containing the appropriate coating material precursors (alkoxides, or metal salts). Coating deposition is via a sol-gel technique. The suspension is sprayed into a hot zone to dry. Coating thicknesses of 10 and 90 nm have been achieved in a single pass. Testing shows that the coated phosphor efficiency is not degraded, while the aging behavior is improved.
