ABSTRACT:
A phosphor for low voltage applications including a plurality of light-emitting particles being made from a UV-excitable light-emitting phosphor, a diffusion barrier being formed as a film on the light-emitting particles, and a coating of an electron-excitable UV-emitting material being formed on the diffusion barrier. A method for making a low voltage phosphor including the steps of (i) providing a UV-excitable light-emitting phosphor (ii) forming a diffusion barrier on the UV-excitable light-emitting phosphor via sol-gel techniques (iii) forming, via sol-gel techniques, a film of an electron-excitable UV-emitting material on the diffusion barrier.
