Infrared fluorescent pigment
Other key words: up converting pigment, IR phosphor, infrared ray active pigment
Infrared phosphor is mainly composed of rare earth inorganic substance (non-toxic and non-radioactive), which does not show color in sunlight and sunlight. It is colorless and transparent, and displays dazzling light when it is irradiated by the infrared ray of 940~1060mm (peak value 980mm). This paint temperature tolerance is wonderful, 60 ° c (long-term) to 800 ° c (2 hours) performance remains the same.
Basic color 3 colors; Blue, green and red.

Description
It is characterized by sensitive response, rich color, long service life, strong concealment performance, high safety performance, convenient and quick detection, etc. It can effectively detect, track, identify and proofread the infrared beam.
Infrared activated anti-counterfeiting phosphor is suitable for all kinds of printing methods, at the same time with any kind of ink mixture will not produce adverse reactions. The product can also be mixed into plastics, paper, cloth, ceramics, glass and solution. Special laser pen or laser detector can be used for detection of this product.
Application of infrared phosphors
- Add ink to make anti-counterfeiting ink and print anti-counterfeiting labels;
- Special detection, such as infrared laser detection board;
- Add plastic film and combine with laser holographic anti-counterfeiting logo to play a comprehensive anti-counterfeiting role;
- For infrared display, infrared detection, biological identification, photovoltaic efficiency and other purposes.
