“…Glass (including silicate glass) containing nanocrystalline particles of lead halides, 9,10 PbS, 11 or PbWO 4 10,12 was described in the past, with the aim to obtain scintillating materials. Lead halides on borate glass are known to undergo the formation of crystallites in controlled conditions, in some cases, using a multicomponent glass matrix.…”

A multicomponent aluminoborosilicate photoluminescent glass was synthesized by introducing Pb(II) and NaBr in its composition. The room-temperature photoluminescence is due to the existence of 4 nm nanocrystals, shown using TEM imaging and XRD analysis, which are assigned to PbBr 2 nanocrystals. The glasses display a broad emission band with a peak at 2.85 eV by exciting at 3.35 eV, with an anisotropy equal to 0.19 at room temperature. At 77 K, the emission intensity increases 1 order of magnitude and a vibronic structure appears, indicating an electron−phonon coupling with the glass matrix. Time-resolved luminescence measurements of these nanocrystals reveal mixed-order kinetics, with second-order recombination of self-trapped electron centers and a first-order temperature-dependent nonradiative rate constant connected with pathways due to confinement of self-trapped centers.

Carbon Nitride Supported Lead Oxide Nanoparticles for Memristor Application: Charge-Transport Mechanism for Resistive Switching

The synthesis of carbon nitride supported lead oxide nanoparticles (CNLO) has been reported by the pyrolysis of urea under ambient pressure and high-temperature conditions in the presence of lead nitrate. The X-ray diffraction analysis confirmed the formation of α-PbO, and the microscopic image showed highly dispersed oxide nanoparticles on the carbon nitride matrix. The optical property exhibited the characteristics vibrational bands that indicate the presence of the graphitic form of carbon nitride structure in the synthesized material. The electrical property of the device made with CNLO, as active material, showed the bipolar resistive switching effect with moderately high ON to OFF ratio, where the transport property of the device was justified by the Poole–Frenkel emission and ohmic conduction mechanism for the low and high conductance states, respectively. The device showed a sustained amount of endurance and retention property with a comparable ON–OFF ratio. The aptitude of processing, storing and recovering of binary information using CNLO based device, with the size of 8-bit, was also demonstrated in this study.

In this paper, some series of lead borate glasses and glass ceramics singly doped with Dy3+ ions were prepared and then studied using spectroscopic techniques. Our research includes mainly studies of the luminescence properties of received materials for white light. The luminescence bands associated with the characteristic 4F9/2→6H15/2 (blue), 4F9/2→6H13/2 (yellow) and 4F9/2→6H11/2 (red) transitions of trivalent dysprosium in lead borate systems are well observed. In particular, the Commission Internationale de I’Eclairage (CIE) chromaticity coordinates (x, y) were calculated in relation to potential applications for white light-emitting diodes (W-LEDs). Their values depend on the relative B2O3/PbO ratios and PbX2 contents (where X = Cl, F, Br) in glass composition. For glass-ceramics, the chromaticity coordinates are changed significantly under different excitation wavelengths.
