Product Application: 4N alumina for fluorescent powder
Rare earth phosphors are commonly used luminescent materials. Rare earth phosphors consist of an activator and a matrix, the former being a rare earth element and the latter being an oxide or salt. In industry, high-temperature solid-phase synthesis is the main method for producing rare earth phosphors. For aluminate-based products, high-purity (hydroxide) aluminum oxide is required. 4N alumina for fluorescent powder are widely used and can be divided into three primary color phosphors for lamps, phosphors for white LEDs, phosphors for display and long-persistence phosphors. The first two are generally used for lighting, which are divided into CRT (cathode ray) phosphors, PDP (plasma display) phosphors and liquid crystal CCFL (cold cathode fluorescent lamps) phosphors.
