Article
The work is focused on the preparation of biluminescent nanoparticles, in which Tb³⁺ and Eu³⁺-doped nanophosphors, based on an inorganic fluoride matrix were covered with luminescent metal nanoclusters of AuAg. Coating the surface of nanophosphors with nanoclusters allows prepared systems to emit light, which color (green/red or orange/red) depends...

In this study, an optical thermometer based on regenerated cellulose fibers modified with YF3: 20% Yb3+, 2% Er3+ nanoparticles was developed. The presented sensor was fabricated by introducing YF3 nanoparticles into cellulose fibers during their formation by the so-called Lyocell process using N-methylmorpholine N-oxide as a direct solvent of cellu...
Article
The increasingly wide-spreading falsification of documents, clothing, and packaging has a negative impact on every aspect of the global markets. Therefore, the development of high-quality strategies for materials protection has become a big challenge. Thus, this work presents novel anti-counterfeiting lyocell fibres, exhibiting bright green or yell...
Article
Cellulose might be a promising material for surface-enhanced Raman scattering (SERS) substrates due to its wide availability, low cost, ease of fabrication, high flexibility and low optical activity. This work shows, for the first time development of the cellulose-based substrate, that owes its SERS activity to the presence of gold nanorods in its...
Article
Optical thermometers are of great interest due to their non-contact, high-sensitivity and fast measurement characteristics. In this work, a series of dual-center Bi1.96-xMoO6: 0.02Er³⁺, 0.02Tm³⁺, xYb³⁺ (x=0.10-0.35) upconverting materials were prepared by a sol-gel synthesis method. Upon 975 nm excitation, the prepared materials exhibit bright colo...
Article
This work sheds the light on the pump power impact on the performance of luminescent thermometers, which is often underestimated by researchers. The up-converting, inorganic nanoluminophore YVO4:Yb3+, Er3+ (nanothermometer) was synthesized using the hydrothermal method and a subsequent calcination. The nanomaterial appears as a white powder compose...
Article
Full-text available
The use of functional nanomaterials and their combination with organic polymers leads to the formation of advanced composites and hybrid inorganic-organic systems having unique properties. The use of such materials as anti-counterfeiting agents (invisible under ambient conditions) is crucial for modern security systems and for further identificatio...
Article
Counterfeiting of valuable documents, currency and branded products is a growing problem that has serious economic and security implications for governments and companies, as well as for ordinary people/customers. In order to prevent and detect falsification, continuous improvement of anticounterfeiting technology is required. This article presents...
Article
Up-converting core@shell type β-NaYF4:Yb3+-Er3+@SiO2 nanorods have been obtained by a two-step synthesis process, which encompasses hydrothermal and microemulsion routes. The synthesized nanomaterial forms stable aqueous colloids and exhibits a bright dual-center emission (λex= 975 nm), i.e. up-conversion luminescence of Er3+ and down-shifting emis...
Article
This article presents synthesis and properties of the fibers modified with luminescent, inorganic nanoparticles doped with lanthanide(III) ions, i.e. LaF3:Ce3+, Gd3+, Eu3+; CeF3:Tb3+ and CePO4:Tb3+. The fibers with luminescent properties were prepared via so called Lyocell process. This method involves dissolving cellulose in aqueous solution of N-...
Article
Full-text available
Novel luminescent–magnetic cellulose microfibers were prepared by a dry–wet spinning method with the use of N-methylmorpholine-N-oxide. The synthesized luminescent–magnetic core/shell type nanostructures, based on the lanthanide-doped fluorides and magnetite nanoparticles (NPs)—Fe3O4/SiO2/NH2/PAA/LnF3, were used as nanomodifiers of the fibers. Than...

• to obtain cellulose fibres and paper – ecological materials, which structure will be modified with luminescent modifiers, ML, synthesized, • to prepare yarn or knitted structure based on modified cellulose fibres, • to synthesize printer inks modified with ML and to get luminescence overprints on paper. In the project research tasks were created: • a synthesis of ML – inorganic micro- and nanophosphors with suitably designed spectroscopic properties, based on rare earth elements, which emit visible light with desired colour, under dual-mode excitation of ultraviolet UV or/and infrared radiation IR, • the synthesis of ML with the use of selected method, including: hydro- and solvothermal reactions, precipitation in the high-boiling solvents and co-precipitation in the presence of compounds preventing agglomeration of the crystallites, • optimization of the preparation method of the cellulose fibres modified with ML and fabrication yarn or knitted structure, • development of the manufacturing process and production of the modified paper, • designing and production of the inks containing ML.
