The main applications of rare earth luminescent materials

The use of rare-earth light-emitting materials will bring the effects of environmental protection and energy saving, good color rendering function and long life number to the light source, which is conducive to promoting the upgrading of products in the current significant area. Therefore, once the rare-earth light-emitting materials are created, they are quickly used in the production of color television picture tubes (CRTs) and fluorescent lamps. The industrial use of rare-earth light-emitting materials in China also began in the [...]

Up-conversion process and mechanism of up-conversion luminescent materials

Its principles include excited state absorption (ESA), energy transfer up conversion (ETU), and photon avalanche (PA). Energy transfer refers to the coupling of two excited ions with similar energy through a non-radiative process, one of which transfers energy to the other and returns to a low energy state, and the other ion receives energy and transitions to a higher energy state. Energy transfer upconversion can occur between the same ions, or between different ions. Therefore, energy transfer up-conversion can [...]

What factors will affect the luminous effect of glow in dark powder printing

Glow in the dark powder printing has become very popular in recent years. Many clothing printing factories have luminous powder printing technology, and luminous clothes are also very popular in the market. Some manufacturers’ technology is not enough, so the printed products have unsatisfactory results. So what are the factors that affect the luminous powder printing effect? Some factors that determine the luminous effect of luminous powder 1.Transparency of ink The luminous effect of the luminous powder of the luminous ink depends on [...]

Application of thermosensitive color change powder in ink

1 selection of connecting material (resin) : 1.1 influence of viscosity and solid content of binder (resin) on color concentration and surface gloss: The choice of resin in ink oil has a very important effect on the color concentration and surface gloss of temperature-varying ink, which is more significant for black ink. Because the content of pigment in the color changing ink is much higher than ordinary ink, if the resin modulation of ordinary ink color changing ink will lead to [...]

Description of luminous effect of invisible fluorescent ink substrate

Because the red fluorescence medium in invisible ultraviolet fluorescent red ink is an organic complex, which is easily decomposed by the metal complex bonds of the fluorescent medium under high temperature and hot flashes, the luminescence period of this fluorescent ink depends on the climate and environmental conditions. Invisible ultraviolet anti – counterfeiting fluorescent red ink Because the red fluorescence medium in invisible ultraviolet fluorescent red ink is an organic complex, which is easily decomposed by the metal complex bonds of [...]

The difference between luminescence, fluorescence and reflection

When the setting sun fades away, when the night falls and the lights come on, I suddenly find that the city at night is so beautiful that compared with the day, it seems to have a soft, romantic charm. As the finishing touch pen, of course, is the light, a variety of, colorful light. Light is different, too. There are spontaneous light, luminescence is a non-thermal emission of materials, the main application field is in the light source, display devices, [...]

How to use glow in dark powder to achieve good results

Glow in the dark powder is a kind of luminous material. But sometimes the user can reflect to use the effect is not good, actually want to make the effect of noctilucent powder better play. Should depend on its actual situation and decide, different requirement, luminance and different use have different use method. Here is a brief introduction. 1 glow in dark powder as a kind of light storage luminous material, so luminous powder again good also have to absorb light. Electric [...]
