The development of new ultraviolet (UV) phosphors is critical to unlocking the full potential UV technologies address global challenges related healthcare, indoor air quality, and environmental sustainability. This work presents effective UV-C Sr3Y(PO4)3:Pr3+ Ba3Y(PO4)3:Pr3+, synthesized by solid-state method. luminescent properties, including both down- upconversion, were investigated under X-ray, UV, visible excitation. Crystallites A3Y(PO4)3 (A = Sr, Ba) activated Pr3+ demonstrate 5d–4f...
Abstract Intrinsic emission of complex oxides with garnet structure was studied by means the analyses time‐resolved luminescence spectra and decay kinetic for single crystals (SC) single‐crystalline films (SCF) Y 3 Al 5 O 12 (YAG) Lu (LuAG) garnets under excitation pulse X‐ray synchrotron radiation at 8–300 K. YAG LuAG SC SCF are characterized significantly different concentration antisite defects (AD) due to substantial difference in conditions their crystallization. For this reason, very...
Research is ongoing to develop new phosphors capable of emitting light across a broad spectrum, ranging from the ultraviolet (UV) infrared region, with potential applications in diverse fields. Using method solid-state reactions, series LiBaF3:Pr3+ were obtained, and their luminescent properties UV–visible range studied. The photon cascade emission (PCE) phenomenon has been observed under excitation 4f5d bands Pr3+. spectral kinetic characteristics X-ray (40 keV) excited luminescence...
Nanopowders of LaPO4 have been grown by sedimentation-micellar method. As-prepared nanoparticles with the average grain size about 8 nm a single-phase hydrated hexagonal structure. After thermal annealing at 600 and 800 °C, increases up to ∼35 ∼50 nm, respectively, structure transforms into monoclinic. IR spectra different were investigated in wide range wavenumbers from 130 5000 cm−1 20–300 K temperature region. Differences between bulk material as well behavior vibrational properties are discussed.
CsPbCl 3 crystal is found to be a promising material for the detection of ionising radiation at low temperatures.
Doping is an effective strategy for enhancing the stability and productivity of perovskite optoelectronic devices. This study presents a first-principles investigation structural, electronic, optical properties Sr-doped CsPbCl3 compared with undoped CsPbCl3. The results demonstrate that retains structure enhanced structural based on tolerance factor dopant formation energy. Sr doping leads to expansion bandgap, which attributed influence dopant’s orbitals original electronic structure, as...
The study of the spectral-luminescence parameters LaPO4-Eu and LaPO4-Pr nanoparticles upon excitation by synchrotron radiation with photon energies 4–40 eV was performed. differences luminescence intensity dependence on size for excited at range matrix transparency, band-to-band transitions, electronic multiplication were revealed. observed regularities are explained in terms electron-phonon electron-electron scattering, surface losses, exciton diffusion. ratio between length thermalization...
The dependence of X-ray excited luminescence intensity on BaF2 nanoparticle size was studied. A sharp decrease self-trapped exciton observed when the is less than 80 nm. main mechanism quenching caused by escape electrons from nanoparticles. Escape nanoparticles confirmed considerable increase polystyrene scintillator with embedded comparing pure scintillator.
The luminescence properties of CaF2 nanoparticles with various sizes (20–140 nm) are studied upon the excitation by VUV and x-ray quanta in order to reveal influence ratio mean free path thermalization length charge carriers nanoparticle size on self-trapped exciton luminescence. intensity for exciting quantum energies corresponding optical creation range electronic multiplication is not so sensitive as energy Eg < hν 2Eg. dependences at discussed terms electron-phonon...
