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...

Research status of fluorescent materials

1. Doping modification: Other ions are added to the traditional fluorescent materials to increase the conversion efficiency and enhance the fluorescence intensity. For example, add the sensitized Yb3+ ions to the fluorescent material. Yb3+ ion has a strong absorption cross section near 980nm, and only has two energy levels, so it will not lose the excitation light energy due to the up-conversion process. Therefore, it is an ideal sensitizer. In particular, lithium ions enhance the fluorescence of rare earth...

LED phosphors: a brief introduction of several phosphors

Ⅰ. Yellow phosphor powder Yellow Phosphors 1. Introduction: YAG phosphor is the fluorescent material of white LED. A blue light chip is coated with a layer of fluorescent substance, and a blue light LED is used to illuminate the fluorescent substance to generate complementary yellow light with blue light. Then the complementary yellow light and blue light are mixed with the principle of lens, and the white light required by the naked eye can be obtained. 2. Product Performance 2.1 The Appearance...

Which watchmaking brands have glow-in-the-dark watch patents

Originally used in watches, noctilucent materials were invented by Panerai. At this time panerai will also be the invention of the patent named their own watch series. There are a lot of friends private message we said before the network spread the kind of watch luminous material, is it true that the radioactive statement, let us take this question together to discuss about the watch luminous material behind the story. Noctilucent material is the most comfortable application in the diving...

There are three common forms of electroluminescence

Gas discharge light source has the following common characteristics: (1) high luminous efficiency. D4101da-r is 2 to 10 times more efficient than incandescent lamps of the same wattage, so it has the characteristics of energy saving. (2) compact structure. The electrodes can be made strong, compact, vibration-resistant, and shock-resistant because they do not emit light from the filament itself. (3) long life. General than incandescent lamp life 2 ~ 10 times longer. (4) strong light and color adaptability. Can vary over a wide...

Characteristics of zinc sulfide short – acting noctilucent powder

Zinc sulfide short - acting luminous powder: product features: "come quickly, go quickly". The so-called "coming fast" refers to the light absorption time is short and sensitive to the source of light, quickly show a luminous effect: "going fast" refers to its short afterglow time. It is easy to show the characteristics of luminous effect, which makes it widely used in many industries and products. Advantages of short-acting noctilucent powder: easy to perform noctilucent effect, the initial brightness is...
