Resumen de: US20260042925A1

The present invention relates to a luminescent ink having a composition in % by weight comprising 20-55% of solvent, 5-55% of diluent; 2-15% of dispersant additive; 5-35% of solid particles with fluorescent properties, and 0.5-15% of solid dopant particles. The invention also relates to a process for obtaining a ceramic product with a printed luminescent label which incorporates a step in which digital printing is performed with said luminescent ink, this printing being applied on the surface substrate of the unfired ceramic part; and wherein the printing is performed with a digital printing machine; subjecting the ceramic part to a subsequent heat treatment in a conventional ceramic furnace at a temperature comprised between 650 and 1400° C.; and obtaining a fired ceramic product comprising a luminescent label visible with ultraviolet light. The invention also relates to a ceramic product obtainable by means of said process for obtaining a ceramic product, as well as to the use of the ink for printing luminescent labels that glow under ultraviolet light on ceramic products.

WO_2026031711_PA

Resumen de: WO2026031711A1

The present invention relates to the technical field of optical anti-counterfeiting. Disclosed are a single-mode excitation color-tunable luminescent upconversion material, and a preparation method therefor and a use thereof in security anti-counterfeiting. The single-mode excitation color-tunable luminescent upconversion material has a molecular formula of AxMOCly-1:Yb/Ln, wherein A is at least one of Li+, Na+, K+, and Cs+, M is at least one of La3+, Y3+, Gd3+, and Lu3+, and Ln is at least one of Er3+, Ho3+, and Tm3+, with 1≤x≤4 and 4≤y≤7. The single-mode excitation color-tunable luminescent upconversion material has an excitation wavelength range of 950 nm to 11000 nm and an emission wavelength range of 400 nm to 800 nm. Under excitation by single-mode near-infrared light, the material exhibits color-tunable upconversion luminescence. The upconversion material has a fast-responsive color-tunable luminescence function, can be used as a high-level security anti-counterfeiting strategy, and is easy and convenient to identify.
