Cluster-like, flower-like and sphere-like EuPO 4 nano/microstructures and uniform core-shell SiO 2 @EuPO 4 nanostructures have been controllably synthesized by the hydrothermal route and co-precipitation method, respectively. The as-synthesized products are characterized by means of X-ray diffraction (XRD), scanning electron microscopy (SEM), transmission electron microscopy (TEM), energy-dispersive spectroscopy (EDS), X-ray photoelectron spectroscopy (XPS) and infrared spectroscopy (IR). The possible formation mechanism of the as-synthesized products is proposed. The photoluminescence properties demonstrate that the locations of the strongest peaks of nano/microstructured EuPO 4 and core-shell

“…Except for nano‐sized fluorescent materials, micrometer‐sized functional materials also played an important role in latent fingerprint recognition. Micrometer‐sized SnO 2 :Eu 3+ nanopowders 33 were synthesized and used to develop latent fingerprints even under severe environmental conditions including aquatic environment and abrasion test. However, in the frequently used luminescent powder‐dusting method, it strongly relies on contact‐model physical brushing with a feather brush to remove the luminescent powder remained in the groove region (i.e., the unadsorbed powder), which is likely to damage fingerprint patterns 16 …”

Latent fingerprints are extremely vital for personal identification and criminal investigation, and potential information recognition techniques have been widely used in the fields of information and communication electronics. Although physical powder dusting methods have been frequently employed to develop latent fingerprints and most of them are carried out by using single component powders of micron‐sized fluorescent particles, magnetic powders, or metal particles, there is still an enormous challenge in producing high‐resolution image of latent fingerprints at different backgrounds or substrates. Herein, a novel and effective nanoimpregnation method is developed to synthesize bifunctional magnetic fluorescent mesoporous microspheres for latent fingerprints visualization by growth of mesoporous silica (mesoSiO2) on magical Fe3O4 core and then deposition of fluorescent YVO4:Eu3+ nanoparticles in the mesopores. The obtained Fe3O4@mesoSiO2@YVO4:Eu3+ microspheres possess spatially isolated magnetic core and fluorescent shell which were insulated by mesoporous silica layer. Due to their small particle size of submicrometer scale, high magnetization and low magnetic remanence as well as the combined magnetic and fluorescent properties, the microspheres show superior performance in visual latent fingerprint recognition with high contrast, high anti‐interference, and sensitivity as well as good retention on multifarious substrates regardless of surface permeability, roughness, refraction, colorfulness, and background fluorescence interference, and it makes them ideal candidates for practical application in fingerprint visualization and even magneto‐optic information storage.

Y₂O₃:Eu³⁺@SiO₂ nanocomposites as a convertor for a broadband solar‐blind UV photodetector

et al. 2022

View full text Add to dashboard Cite

Core–shell nanocomposites have attracted extensive attention in the photoelectric field because of their improved material properties and the combination of multiple functions. Particularly, these nanocomposites exhibit tunable structure and excellent optical properties. Inspired by these unique features, a novel optically active nanocomposites, Y2O3:Eu3+@SiO2 with a core–shell structure, is designed and fabricated by a hydrothermal method and electrophoretic deposition. In addition, the Y2O3:Eu3+@SiO2 composite film is also successfully developed and applied as a spectral down‐converter in the solar‐blind ultraviolet (UV) waveband region of 200–280 nm. Moreover, a broadband solar‐blind UV photodetector device is elaborated and a notable enhancement in the UV sensitivity is achieved. The findings not only provide a new idea for the development of broadband solar‐blind UV photodetector but also extended the application range of core–shell nanocomposites in photonics.
