Types of electroluminescence

Electroluminescence is also known as field luminescence. Electroluminescence is a kind of luminescence phenomenon in which electric energy is directly converted into light energy. It includes injection electroluminescence and intrinsic electroluminescence. (1) Injection electroluminescence: electrons and holes are injected directly by the electrode mounted on the crystal. When the electrons and holes are recombined in the crystal, excess energy is released in the form of light. The basic structure of injection electroluminescence is junction diode (LED). (2) Intrinsic electroluminescence: it can [...]

About photochromatic materials

I. Basic knowledge of spectrum: ULTRAVIOLET rays are divided into three types according to different bands: UVC for those with a wavelength below 250 nm, UVB for those with a wavelength between 250 and 320 nm, and UVA for those with a wavelength between 320 and 380. The visible light range is 380-800 (nm) and the infrared light range is 900-1800 (nm). Two, photochromic principle: the use of UVA energy to open the photosensitive molecular bonds, so that it from [...]

A new red luminescent powder and a method for making red luminescent ceramics

A new red luminescent powder is composed of BEiyQia8_x_yZnxTi03:aPr3+, bLu3+, cNa+ and dB3+, with titanate as the substrate, Pr3+ as the activator and Lu3+ as the sensitizer. The luminous powder is used to prepare the luminous red ceramics. The best known green luminescent powder is SrAl2O4 = Eu2+ and Dy3+, while the blue luminescent powder is SrAl2O4 = Eu2+ and Nd3+. The chemical properties, afterglow intensity and attenuation time of these two luminescent powder are similar. But there is no [...]

Do you know about luminance and duration characteristics of glow in dark powder

About the brightness of luminous powder in the new customers often have doubts, clearly said that the manufacturer can be bright for 10 hours how to see half an hour, causing some unnecessary misunderstanding. The luminance of luminescent materials is usually measured in units of CD /m2(candela per square meter), while noctilucent powders are usually measured in units of MCD /m2(Millicandela per square meter). The midday sun reaches 10,000 to 100,000 CDS /m2, In the daytime, there are only 1000 ~ 5000cd/m2 [...]
