China (Mainland) Up Conversion Luminescent Anti-forgery Label

Place of Origin	China
Model Number	Up Conversion Luminescent Anti-forgery

Specifications: Up-conversion luminescent anti-forgery materials convert various invisible ir wave band light to visible light. The up-conversion luminescent anti-forgery material, that kpt open it out one and only in china, is combined with skill advantage in chinese academy of sciences. The quality of it has reached one-up level all over the world. There are different characteristics on these products: Sensitive response, abundant color, long lifetime and high quality of security. Up-conversion luminescent anti-forgery materials are effective for ir beam to detect, track, proof and identify. The exploitation of this product has been given the national invention award and the national important auspice The granularity of up-conversion luminescent anti-forgery material that belonging to powder in kpt range from 400nm-10m. The excitated power is 1mw and effective excitated wave band is from 900 to 1060nm. Besides, up-conversion luminescent anti-forgery material is suitable for all kinds of print ink. The basic guideline of up-conversion luminescent anti-forgery material in kpt: Element rare earth mineral(no poison) Average granularity 0.4-10 micron(smaller based on special requirement) Endurance for friction and humidity good Endurance for temperature quality no change from -50(long time) to 1300(1hour) Endurance for ultraviolet radiation best Endurance for acid and alkali best Stability no reaction on organic impregnant Coalescence with ink no change happened when combined with colorless or other color ink Lifetime more than 50 years Color white or tiny powder with white color Specific gravity 3.0-5.0 Excitated spectrum 900-1060nm(peak value 980 nm) Emitted spectrum red 610-630nm blue 430-470nm green 530-560 nm Other color whole bestrow(adjustable) or change color Excitated lamp-house laser emitter(10mw)/ir led(30mw)
