Type-II p-n junction three-dimensional Ag(2)O/TiO(2) microspheres have been fabricated by assembling p-type Ag(2)O nanoparticle on n-type TiO(2) 3D microsphere. microsphere nanoheterojunctions were obtained hydrothermal synthesis of at 180 °C followed photoreduction AgNO(3). The samples carefully characterized X-ray diffraction (XRD), transmission electron microscopy (TEM), field-emission scanning (FESEM), and energy dispersive analysis (EDX). photocatalytic activity toward degradation...
Graphene quantum dots are known to exhibit tunable photoluminescence (PL) through manipulation of edge functionality under various synthesis conditions. Here, we report observation excitation dependent anomalous m–n type fingerprint PL transition in synthesized amino functionalized graphene (5–7 nm). The effect band-to-band π*–π and interstate band n–π induced transitions led effective multicolor emission changeable wavelength the system. A reasonable assertion that equi-coupling activated...
Stoichiometric NiO, a Mott–Hubbard insulator at room temperature, shows p-type electrical conduction due to the introduction of Ni2+ vacancies (VNi'') and self-doping Ni3+ ions in presence excess oxygen. The conductivity this important material is low not sufficient for active device fabrication. Al doped NiO thin films were synthesized by radio frequency (RF) magnetron sputtering on glass substrates substrate temperature 250 °C an oxygen + argon atmosphere order enhance conductivity. X-ray...
Morphology controlled hierarchical ZnO/CuO architecture was obtained on both flexible and rigid substrates, which exhibited excellent photocatalytic performance by virtue of favourable heterojunction formation at nanostructure interfaces.
Highly-luminescent nanophosphors have a decisive role in solid-state lighting (SSL) as well field emission display (FED) applications due to their potential use fabrication of nanophosphor based FED and solid state devices. Herein, the red emitting highly-luminescent Eu3+–Li+ co-doped magnesium aluminate (MgAl2O4) were synthesized by customized sol–gel route with an average particle size 18 nm, which can be easily scaled up large quantity. The resulting exhibits hypersensitive emission,...
The spherical assembly of nanoparticles induces a high degree alignment magnetic easy axis as compared to randomly oriented which increases the reduced remanence ensuing straightened hysteresis loop.
A comprehensive review is given on recent developments of multidimensional nanostructural ZnO processed <italic>via</italic> low temperature solution approaches and their functional prospect in field emission environmental remediation.
Solid-state lighting (SSL) and field emission based display (FED) devices collectively encompass a major fraction of contemporary research efforts thus development newer generation highly luminescent nanophosphors presently defines critical juncture for further this still somewhat-nascent field. However, the low efficiency red phosphors constitutes principal bottleneck commercialization such devices. Herein, we present light emitting Na+ codoped CaSnO3:Eu3+ nanophosphor with an average...
We demonstrate an easy and scalable room-temperature synthesis of Cu2O nanoparticle incorporated graphitic carbon nitride composites without the aid any inert atmosphere. First principles calculations based upon density functional theory, in addition to experimental validations, have been employed investigate electronic optical properties nanocomposites. An insight into band structure tunability, phase stabilisation dependancy catalytic nanocomposites amount Cu loading, form oxides, provided...
With the contemplations of ecological and environmental issues related to energy harvesting, piezoelectric nanogenerators (PNGs) may be an accessible, sustainable, abundant elective wellspring in future. The PNGs' power output, however, is dependent on mechanical input, which will intermittent if not continuous. This a fatal flaw for electronics that need continuous power. Here, self-charging flexible supercapacitor (PSCFS) successfully realized can harvest sporadic energy, convert it...
For several decades, the development of potential flexible electronics, such as electronic skin, wearable technology, environmental monitoring systems, and internet Things network, has been emphasized. In this context, piezoelectric nanogenerators (PENGs) triboelectric (TENGs) are highly regarded due to their simple design, high output performance, cost-effectiveness. On a smaller scale, self-powered sensor research based on piezo-triboelectric hybrid have lately become more popular. When...
