Special Issue Information

Dear Colleagues,

Nanomaterials have been attracting considerable interest due to their unique physicochemical properties, which differ from their bulk materials. Among them, fluorescent nanomaterials with both characteristics of fluorescence and nanomaterials demonstrate their great potential in a wide variety of applications, such as biosensing, bioimaging, theranostics, anti-counterfeiting, illumination, etc. With the rapid development of nanoscience and nanotechnology, more and more strategies have emerged for the design, synthesis, characterization, functionalization, and application of different kinds of fluorescent nanomaterials. In this Special Issue on “Fluorescent Nanomaterials: Synthesis and Applications”, we invite reviews, research articles, and communications on recent advances in the abovementioned topics on fluorescent nanomaterials and their nanocomposites.

The potential topics for this Special Issue include but are not limited to:

  • New design, synthesis, and characterization methods for fluorescent nanomaterials and nanocomposites;
  • Novel strategies for efficient modification and functionalization of fluorescent nanomaterials and nanocomposites;
  • Fundamental research on fluorescent nanomaterials’ physicochemical properties and their mechanisms;
  • Applications of fluorescent nanomaterials in a variety of fields, including biosensing, bioimaging, theranostics, anti-counterfeiting, illumination, et

Abstract
This work presents a highly secure anticounterfeiting strategy based on upconversion/afterglow hybrids with tricolor emissions tuned by a single 975 nm laser. The hybrids are composed of NaYF4:Yb/Tm and NaYF4:Yb/Er microrods and CaS:Eu2+ afterglow phosphors. Under 975 nm [...] Read more.
This work presents a highly secure anticounterfeiting strategy based on upconversion/afterglow hybrids with tricolor emissions tuned by a single 975 nm laser. The hybrids are composed of NaYF4:Yb/Tm and NaYF4:Yb/Er microrods and CaS:Eu2+ afterglow phosphors. Under 975 nm excitation, the hybrids exhibit multicolor emissions from green to white by adjusting laser power and then emit red afterglow light when the 975 nm laser is off. Under synergistic excitation of the blue-green light emitted by Tm/Er microrods, the red afterglow emission not only has a strong initial intensity but also lasts for 3 s. Obvious trichromatic changes from green to white to red can be observed by the naked eye. A pattern printed by the hybrid ink exhibits tricolor emissions by laser adjustment and switch. This proves that upconversion/afterglow hybrids are an excellent candidate for anticounterfeiting applications with high-level security but a simple recognition method. Full article

A high-luminescent, blue-light excitable europium(III) coordination complex, [Eu(µ2-OC2H5)(btfa)(NO3)(phen)]2phen (1) {btfa = benzoyl trifluoroacetone, phen = 1,10-phenantroline}, has been synthesized and investigated. The complex was characterized by infrared (IR) and photoluminescence (PL) spectroscopy. The PL emission spectra of powder samples registered in a range of 10.7–300 K exhibit characteristic metal-centered luminescence bands, assigned to internal radiative transitions of the Eu3+ ion, 5D1→7Fj and 5D0→7Fj (j = 0–4). The high-resolution spectrum of the transition 5D0→7F0 shows that it consists of two narrow components, separated by 0.96 meV, which indicates the presence in the matrix of two different sites of the Eu3+ ion. The splitting pattern of 5D0→7Fj (j = 0–4) transitions indicates that europium ions are located in a low-symmetry environment. The absolute quantum yield and the sensitization efficiency were determined to be 49.2% and 89.3%, respectively. The complex can be excited with low-cost lasers at around 405 nm and is attractive for potential applications in optoelectronics and biochemistry. Full article
