A coating technology for forming a nano-thickness hydrophobic polymer on upconversion nanophoshpors was developed. A mixed resin with pentaerythritol tetraacrylate and triethyleneglycol dimethacrylate was photocured on the surface of the upconversion phosphor particles with 200 nm size to form a solid coating film with 80 nm. According to the FE-SEM observation, the particles are found to be caoted serparately each other.
