Latest Patents
Weijian Shen holds a patent titled "Preparation of concealed marks with core-shell luminophores for customs security check system and application thereof." This invention focuses on the preparation of concealed marks using core-shell luminophores to enhance customs security checks. The patent addresses the limitations of infrared luminescent materials, which have not been effectively utilized in customs clearance. The current infrared luminescent materials have insufficient absorption cross sections and low upconversion luminescence intensity, leading to unclear luminescent marks. Shen's solution involves a multi-step process: preparing TiQ, creating Ag@TiO composite nanoparticles, synthesizing Ag@TiQ@NaYF:Yb, Er luminescent nanoparticles, and ultimately making concealed luggage marks. The resulting Ag@TiQ@NaYF:Yb, Er luminescent nanoparticles exhibit superior luminescent intensity compared to pure NaYF:Yb, Er, and can be dispersed in organic solutions like ethanol and methanol for effective use in marking susceptible luggage. This innovation provides a promising direction for senseless, intelligent, and safe customs clearance.
