New synthetic routes using controlled precipitation and firing have led to the preparation of submicron phosphors. In this way, fine particle (0.25–0.5μm) phosphors have been prepared. These compare favourably to present industrial phosphors (3–8μm) with respect to efficiency and brightness at low voltage (300–5000V). The work is now being extended to oxides and binary and ternary sulphides, with considerable promise, although further optimisation is still required.
