The main advantages of organic photochromic compounds used in optical information storage media are as follows:(1) High storage density and large storage capacity. Organic materials use molecular changes to record information, which can realize molecular memory in theory. (2) High sensitivity and fast response, which can reach nanosecond… Read More »Organic photochromic compounds are used as optical storage media
Self-luminous coatings, as a new type of coating that has emerged in recent years, have attracted widespread attention and application. Currently, the most common applications include starlight roads, fluorescent roads, night-luminous roads, permeable roads, and cement roads. Many users have doubts about the wear resistance and service life… Read More »How good is the wear resistance of self-luminous paint?
Photochromic materials refer to materials with photochromic properties. Photochromism, that is, some substances will change color under the irradiation of ultraviolet light or visible light, and when the light disappears, they will change to the original color reversibly. It is also called “photochromism” or “photochromism”. Photochromic properties can… Read More »Application of photochromic materials in textiles
Plastic noctilucent refers to a plastic additive which can be absorbed by sunlight or other light after being added to plastic, store light energy and automatically emit light in the dark.At present, there are two main types of plastic luminous agents: one is metal sulfide, which is the… Read More »What is a plastic luminous agent?

Photochromism is a chemical and physical phenomenon, including light-induced chemical and physical reactions of organic, inorganic, biological and polymer.In 1867, Fritsche observed the fading phenomenon of yellow tetracene under the action of air and light, and the generated substance was regenerated into tetracene when heated. In 1876, Meer… Read More »Development history of photochromic research
Photoluminescent pigments is a kind of material that can emit light in dark environment, and it can realize its own luminous function by absorbing visible light, and this function of self-luminous is not one-off, but can be repeated. Since luminescent powder contains no radioactive elements, it is often… Read More »Method for producing photoluminescent pigments
Microfiber synthetic leather, referred to as microfiber leather for short, is made by breaking the leftover material of the first layer of cowhide, adding resin composed of nylon microfiber and polyurethane in proportion to make leather pulp, then making it into “leather embryos” by mechanical calendering, and then… Read More »Method for making poly urethane leather with luminous effect
Luminous ceramics is a very popular handicraft now, which is deeply loved and sought after by young people. However, the sintered ceramics need to be in an oxidizing atmosphere. If the luminous powder is directly used in it, it will be oxidized, thus losing its luminous function. This… Read More »How to make luminous ceramic products with glow powder

The upconversion luminescence process is an Anti-Stokes process, that is, luminescent ions emit short waves (visible light) by absorbing multiple long waves (infrared light). Up-conversion luminescence mechanisms include excited state absorption (ESA), energy transfer (ET), cross relaxation (CR), synergistic sensitization (CSU) and photon avalanche (PA). The schematic diagram… Read More »Upconversion luminescence process and luminescence mechanism
