Multi-level, dynamic optical anti-counterfeiting has been achieved using multi-mode phosphors as luminescent inks. The ZGGO:Cr,Yb,Er exhibit quintuple luminescence modes, while the ZLGO:Mn possess quadruple modes.
Abstract UV‐charged optical stimulated single‐band phosphors are being used for single‐level data storage because of their ability to easily write/read information by light. In contrast, UV–visible–NIR rechargeable double‐band phosphor is urgently necessary multiplexed high‐throughput storage. Here, the authors design and synthesize Mn 2+ ,Cr 3+ co‐doped zinc gallate persistent that exhibits strong red‐green bicolor luminescence (PersL). Besides traditional ultraviolet charging, can be...
Fluorescence latent fingerprinting (LFP) imaging is a convenient and frequently used in situ detection technique. In recent years, various types of phosphors have been widely for LFP imaging. However, traditional phosphor powders are suffering from formidable challenge to design effective fluorescent with low background interference high sensitivity. this work, we synthesized Zn2GeO4:Mn,Li,K (ZGO:Mn,Li,K) nanophosphors the persistent luminescence (PersL) brightness long duration using...
Ho3+-Yb3+ co-doped bismuth titanate ferroelectric thin films were prepared by a chemical solution deposition method on fused silica substrates and their up-conversion luminescence characteristics excited 980 nm diode laser investigated. The two emission bands centered at 546 656 in the spectra can be assigned to 5F4 + 5S2 → 5I8 5F5 transitions of Ho3+ ions, respectively. A bright green was observed even when pumping power relatively low. dependence intensity indicated that two-photon...
A magnetic amine-functionalized polyacrylic acid-nanomagnetite adsorbent is developed for the removal of toxic hexavalent chromium from polluted water.
ZnAl layered double hydroxides (LDHs) film was prepared on the pure Al by an in-situ growth method. In-situ observation of behavior ZnAl-LDHs-NO3 studied electrochemical quartz crystal microbalance (EQCM) and open circuit potential (OCP). The characteristics analyzed through X-ray diffraction, photoelectron spectroscopy scanning electronic microscope. corrosion LDHs investigated impedance polarization curves. results indicate that process can be divided into dissolution substrate stage,...
Photostimulable luminescence (PSL) nanophosphors, which exhibit superior features including controllable energy storage and efficient photon release upon light stimulation, are desirable for optical signal storage. However, trap tuning of the phosphor remains a great challenge. Herein, PSL Zn2GeO4:Mn2+ nanophosphors is enhanced via creating deep traps through nonequivalent Pr3+ doping. The possible mechanisms analyzed combined with doping models using first-principles theory. A mechanism...
We have developed a hybrid chemical solution method for preparing nanocomposite thin films composed of ferroelectric Bi(3.6)Eu(0.4)Ti(3)O(12) (BEuT) matrix and highly c-axis-oriented ZnO nanorods on Si substrates. First, seed-layer growth approach was used to prepare the nanorods, then deposition employed fabricate BEuT by coating using spin-coating technique. The obtained exhibited significantly enhanced red photoluminescence (PL) properties. PL enhancement can be attributed very efficient...
Strong upconversion green luminescence was observed in Er3+ and Yb3+ codoped Bi4Ti3O12 ferroelectric thin films. The films were prepared on fused silica Pt/TiO2/SiO2/Si substrates by chemical solution deposition method. There are two strong emission bands centered at 524 545 nm a weak red band 667 the spectra pumped 980 room temperature. They correspond to radiative relaxation of from H211/2, S43/2, F49/2 levels ground level I415/2, respectively. Bi3.65Yb0.3Er0.05Ti3O12 exhibit higher...
Up to 37-fold enhanced luminescence was achieved when NaY(MoO<sub>4</sub>)<sub>2</sub>:Yb<sup>3+</sup>/Er<sup>3+</sup> micro-crystals were annealed at 700 °C. Their high-purity green emission makes them suitable for the imaging of latent fingerprints and anti-counterfeiting applications.
