Resumen de: US20260285078A1
A method of making a magnetic security feature. A layer of ink comprising a first set of particles and a second set of particles in suspension within the liquid ink is printed onto a substrate. The particles are magnetically anisotropic and acicular. A permanent magnet is moved along the printed ink layer, followed by an electromagnet which is turned on and off selectively as it is moved along the printed ink layer. The electromagnet has a magnetic field strength which is higher than the coercivity of the particles of the second set but lower than the particle of the first set. The resulting magnetic security feature has a magnetic pattern across it, which has subtle differences between areas over which the electromagnet was turned off versus those over which it was turned on that are harder for counterfeiters to notice and/or copy.

The present invention relates to the synthesis of europium-doped strontium magnesium germanate phosphors and, in more particular manner, to a process for the synthesis of Sr2MgGe2O7:xEu3+ (SMGO:xEu3+) phosphors (where x=0.5-6 mol %) for white LEDs, latent fingerprint detection, and anti-counterfeiting applications. The synthesis is carried out by mixing Stoichiometric molar amounts of strontium nitrate (Sr(NO3)2), magnesium nitrate (Mg(NO3)2·6H2O), germanium dioxide (GeO2), and europium nitrate (Eu(NO3)3·6H2O) were dissolved in deionized water, and further adding Aloe vera gel extract as a natural fuel, wherein the resultant solution is stirred to obtain a homogeneous redox mixture, which then boiled, ignited to form a gel, and combusted into a fine powder, wherein the fine powder is then annealed for improve crystallinity. These results substantiate the efficacy of SMGO:Eu3+ phosphor as a viable forensic material for high-resolution LFP detection, offering a compelling alternative to existing commercial powders, especially under UV-assisted visualization scenarios
