For vacuum detection and satellite to provide auxiliary energy. Pm147 gives off rays of low energy to make promethium batteries. Power for missile guidance instruments and clocks. The batteries are small and can last for years. Promethium [...]

Introduction of various types phosphorescent materials

Phosphor types use a phosphor “phosphor” “Inorganic powder material at a certain excitation conditions can be light, sometimes also called light pink, crystalline phosphors or phosphor according to the type of excitation mode can be divided into organic light-emitting phosphor, the electroluminescent phosphor, cathode ray luminescent phosphors and phosphor luminescence radiation and so on. 2 photoluminescent phosphors “photo luminescent phosphor” Emitting excitation light can be an inorganic powder material. Excitation light can be ultraviolet, visible, near-infrared bands. 3 fluorescent high pressure mercury lamp phosphors [...]
