Synthesis method of long afterglow materials

High temperature solid phase reaction method Long afterglow which was prepared by using high temperature solid instead should process is: according to the calculation of the mole ratio of says take spectrum pure co: A120, sr - and Eu203 raw material, and after a certain amount of canadians flux blending fine grinding, first by 1500 ℃ calcination 3 hours, then in the reduction of gas and 1200 ℃ 1400 ℃ roasting 2 one 4 hours, only made larger phosphor,...

Instructions for the use of long-acting luminous powder, technical indicators

Long-term luminous powder soil type belong to alkaline earth aluminate long afterglow luminescence materials, components can be expressed as: Al2O3 · (Sr, Mg, Ca) O: (Eu, La, Dy) B, can be in the sun or light absorbance 5-20 minutes later, will absorb the light energy stored in the crystal lattice, after can convert the energy into light energy in the dark and light, which can effectively sustained glow (luminescence brightness is more than 10 MCD/m2) to 8 to 10...

Introduction of various types phosphorescent materials

"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 "phosphor for high pressure mercury...
