Red frequency-upconversion fluorescence emission is observed in europium (III) complex with encapsulating polybenzimidazole tripodal ligands, pumped with 930- and 1070-nm picosecond laser pulses. The luminescence of transition 5D0->7F2 (612 nm) is
Optically transparent Er3+-doped tellurite-based nanocrystallized glasses with the composition of 70TeO2-15Li2O-15Nb2O5-0.5Er2O3 (mol) have been prepared by a conventional melting quenching and the subsequent heat treatment processes. The sizes of gr
Light-emitting silicon nanocrystals are prepared by the pyrolysis of silane and subsequent controlled size-reduction by chemical etching. These nanocrystals show luminescence tunable through the full visible spectral region. The luminescence rate inc
Two new iridium organometallic compounds based on acetylacetone derivative ligands containing carrier-transporting groups, Ir(L)(2)(acac-Ox) and Ir(L)(2)(acac-Cz), where L = 3-(pyridin-2-yl)coumarinato N, C-4, acac-Ox = 3-(4-(5-(4'-tert-butylphenyl)-
Silica-based Yb3+-doped glass is prepared by non-chemical vapor deposition. The drawn photonic crystal fiber (PCF) has a strong absorption at 976 nm and emission wavelength of approximately 1 037 nm. The intensity and spectral lineshape of the near i
Cone beam X-ray luminescence computed tomography (CB-XLCT) has been proposed as a promising hybrid imaging technique. Though it has the advantage of fast imaging, the inverse problem of CB-XLCT is seriously ill-conditioned, making the image quality q
This paper describes an overview of our recent discovery – clear demonstration that LiF crystals can be efficiently used as a high-performance neutron imaging detector based on optically stimulated luminescence of color centers generated by neutron i
Fully concentrated Yb-based LiYb(MoO4)2 phosphor was prepared by solid state reaction method. The sample was characterized by XRD measurement, SEM and photoluminescence measurements. It presents bright blue emission at around 478 nm under the ex
