“…Therefore, fluorescent materials with superior optical qualities, chemical resistance, and distinctive physical features are urgently needed as anticounterfeiting agents. Fluorescent materials are a wide range of organic and inorganic compounds, such as rare-earth compounds as well as doped nanostructured rare-earth compounds [2][3][4][5][6], quantum dots [7], and so on. All these compounds have been extensively studied in anti-counterfeiting applications because of their ability to show bright fluorescent emission in different colors.…”

The growing demand for optical anti-counterfeiting technology requires the development of new environmentally-friendly smart materials with single-component, multimodal fluorescence. Herein, Cs2ZnBr4:0.3Mn2+&0.15Cu+, as an efficient multimodal luminescent material with excitation-wavelength-dependent emission is reported. Under 365 nm and 254 nm UV light excitation, Cs2ZnBr4: Mn2+&Cu+ emits mutually independent green light at 525 nm and blue light at 470 nm , which origin from the emission of Mn2+ and the Cu+ enhanced self-trapped excitons of Cs2ZnBr4, respectively. Furthermore, the multiexcitonic emission is applied to anti-counterfeiting applications and information encryption and decryption engineering. This codoped stratergy provides a colorful step to expand the new metal halide materials in fluorescent anti-counterfeiting and information encryption and decryption.

A sensitive voltammetric technique for the determination of avanafil (AVA) has been investigated at a carbon paste electrode modified with Zinc oxide nanoparticles and multi-walled carbon nanotubes (ZnO-NPs/MWCNT/CP). The study investigated the electrochemical behavior of AVA, and the morphology of the modified electrode was evaluated by transmission electron microscopy, scanning electron microscopy, and X-ray diffraction patterns. The influence of different electrodes and the content of ZnO-NPs on the voltammetric behavior of AVA were evaluated. Square wave voltammetry was studied and a linear correlation resulted within the range of (1.3-16 μg ml −1 ) with correlation coefficient 0.999, LOD 0.342 μg ml −1 and LOQ 1.141 μg ml −1 . The proposed procedure was applied successfully for the determination of AVA with good recovery in commercial dosage form and human plasma. The technique was validated and found to be accurate and reproducible according to the ICH guidelines.

“…Moreover, Bavasso et al [15] proposed the generation of highly oxidizing radical species through reaction systems that combine the presence of UV radiation with species such as ozone and hydrogen peroxide, susceptible to suffer photolysis processes. Likewise, Singh et al [16][17][18][19] successfully employed Pr, Eu or Pd in different titania structures for several applications in accordance to their optical properties, for example to degrade a harmful dye. These results show the numerous attempts that have been developed, constituting moreover an interesting challenge to optimize the reaction systems towards milder conditions.…”

A Promising Alternative for Aqueous Effluents Treatment: Modified Mesoporous Materials that are Photoactive under LED Visible Radiation.

TiO2 nanoparticles co‐doped with iron and carbon were tested in photocatalytic processes using visible radiation to degrade Acid Orange 7 and Paracetamol from aqueous solutions. In our previous reports, the mesoporosity and crystallinity of the samples were analyzed along with the calcination temperature effect. In this work, it was possible to verify the efficiency of a synergistic effect between dopants when a calcination at 150 °C was applied, favoring their localization in key sites of titania structure which improves the response under visible light. Such accomplishments could be also confirmed through photoluminescence analysis. Thus, the optimized solid showed an enhanced photocatalytic performance, reaching at only one hour of reaction, a complete degradation of both dye and drug while some intermediate species were reduced according to mineralization degree (around 80 %), and biodegradability achieved. Therefore, the proposed photocatalytic system presents potential as a previous step to a biological treatment for aqueous effluents.
