Description
Technical field
The present invention relates to a kind of anti-forgery ink that possesses composite anti-fake function, especially adopt the photosensitive anti-forgery ink of rare earth luminescent material as photoactivation compound.
Background technology
Anti-forgery ink (anti-forgery ink) refers to that the ink changing a lot under special conditions is in order to be printed in ticket, product brand and packing, produce visible or sightless mark, by applying different ambient conditions, as forms such as illumination, heating, spectral detection, observe the color change of ink pull, be convenient to verification and prevent from forging, reaching false proof object.Anti-fraud functional compound be one of effective way of improving false proof barrier and factor of assurance.
Rare earth luminously mainly contain at present two kinds of up-conversion luminescence and lower conversion luminescences for false proof theory and method.The theoretical infrared excitation luminescent material corresponding to method of up-conversion luminescence, the theoretical corresponding burst of ultraviolel luminescent material of lower conversion luminescence and method.Infrared excitation luminescent material has the colors such as red, green, yellow, blue by the infrared ray excited visible light colors of sending.Burst of ultraviolel luminescent material divides 2 kinds, one is can send visible ray under short wave ultraviolet light excites, have or not-yellow, orange, red, yellowish green, emerald green, grass green, dark green, bright blue, reddish blue, black, red-orange, red-red, green-grass green, blue-grass green, orange-red, yellow-red, black-red, green-red, blue-red, orange-orange of glow color, indigo plant-green, yellow-yellow, indigo plant-blue, green-yellowish green; Another kind is under long wave ultraviolet light excites, and can send visible ray.It is colourless, yellow, orange, red, green that glow color has etc.Although the multi-selection of its glow color provides better approach for improving antiforge function.But current upper efficiency of conversion is extremely low, even best up-conversion NaYF4:2%Er3+, the upper efficiency of conversion of 18%Yb3+ just has 3%, and this has seriously restricted its application.Affect the display brightness of the mark of anti-forgery ink printing, reduced the identifiability of anti-counterfeiting mark.Chinese invention patent document CN1O1942306B discloses the patent of invention that name is called " having material of cooperative frequency light conversion performance and preparation method thereof and application ", the molecular formula of this material is: YxYby(∑ Ln) zF3,0≤x<1, O<y<1, O<Z≤0.50, Ln be in rare earth element ce, Tm, Er, Ho, Dy, Tb, Gd, Eu, Sm, Nd, Pr any one or several arbitrarily.The preparation method of this material adopts any one in conventional high temperature solid-state method, hydrothermal synthesis method or coprecipitation method.This material has been realized and under upper conversion and quantum-cutting, has been changed two kinds of machine-processed combinations, effectively UV-light and infrared light have been transformed into the visible ray of a certain frequency simultaneously, and have obtained the enhancing that the visible light intensity of this frequency is greater than 2 times, cost is low, simple synthetic method, can manufacture.What this invention was emphasized is this material is in the application of preparing in solar-energy photo-voltaic cell, to its objective is in order solving in the switching process that prior art exists and to produce heat effect, photovoltaic device produced to the problem of infringement; And improve solar-energy photo-voltaic cell efficiency.Can effectively improve anti-forgery ink performance if be applied to anti-forgery ink.But this solar-energy photo-voltaic cell type material is applied to the false proof field of ink, needs feasibility study, and will meet the requirement of physico-chemical property and the printability aspect of ink.
