What is blue light?
What is blue light? The Sun bathes us daily in light, which is one of many types of electromagnetic radiation, along with radio waves, microwaves and gamma rays. We can’t see the vast majority of these energy waves flowing through space, but we can measure them. The light that human eyes can see,...Read more -
IR-Reflective Pigment for Infrared Reflective Coating
While the human eye is sensitive to only a small part of the electromagnetic spectrum, pigment interactions with wavelengths outside the visible can have interesting effects on coating properties. The primary purpose of IR-reflective coatings is to keep objects cooler than they would be using sta...Read more -

Discussion on near infrared absorption anti – counterfeiting ink
Near-infrared absorption anti-counterfeiting ink is made of one or several near-infrared absorption materials added to ink. Near-infrared absorption material is an organic functional dye. It has absorption in the near infrared region, the maximum absorption wavelength 700nm ~ 1100nm, and the osci...Read more -
Characteristics of ultraviolet fluorescent anti-counterfeiting powder
Ultraviolet fluorescent anti-counterfeiting powder (also called invisible anti-counterfeiting pigment) appearance is white or colorless powder, through the wavelength of 200-400nm ultraviolet fluorescent lamp irradiation, display light color (fluorescent anti-counterfeiting red, fluorescent anti-...Read more -
Classification and distinction of ultraviolet phosphors
Ultraviolet phosphor can be divided into inorganic phosphor and organic fluorescent invisible powder according to its source. Inorganic phosphor belongs to inorganic compound with fine spherical particles and easy dispersion, with 98% diameter of about 1-10U. It has good solvent resistance, acid ...Read more -
Is luminous powder the same as phosphor (fluorescent pigment)?
Is luminous powder the same as phosphor (fluorescent pigment)? Noctilucent powder is called fluorescent powder, because when it is luminous, it is not particularly bright, on the contrary, it is particularly soft, so it is called fluorescent powder. But there is another type of phosphor in the ...Read more -
NIR fluorescent dyes near-infrared absorption dye
NIR fluorescent dyes are widely used in night vision, invisible materials, laser printing, solar cells and other fields because of their absorption in the NIR region (750 ~ 2500nm). When used in biological imaging, it has near-infrared absorption/emission wavelength, excellent water solubility, l...Read more -

Upconversion luminescent materials
Upconversion luminescence, namely, anti-Stokes luminescence, means that the material is excited by low energy light and emits high energy light, that is, the material emits short wavelength and high frequency light excited by long wavelength and low frequency light. Upconversion luminescence Acco...Read more -
Photochromic polymer
Photochromic polymer materials are polymers containing chromatic groups that change color when irradiated by light of a certain wavelength and then return to the original color under the action of light or heat of another wavelength. Photochromic polymer materials have attracted widespread intere...Read more -
