“…A flexible ZnO energy harvester and nanogenerator can generate electrical energy by large deformation under stretching or compression load due to the substrate flexibility [33,34]. A flexible ZnO strain sensor can be utilized to structure a health monitoring system of arbitrarily shaped structures [35,36]. Polymer-based ZnO thin film transistors, surface acoustic wave devices and dye-sensitized solar cells can be realized by applying flexible electronics [37–39].…”

This paper reports the synthesis and UV sensing characteristics of a cellulose and ZnO hybrid nanocomposite (CEZOHN) prepared by exploiting the synergetic effects of ZnO functionality and the renewability of cellulose. Vertically aligned ZnO nanorods were grown well on a flexible cellulose film by direct ZnO seeding and hydrothermal growing processes. The ZnO nanorods have the wurtzite structure and an aspect ratio of 9 ~ 11. Photoresponse of the prepared CEZOHN was evaluated by measuring photocurrent under UV illumination. CEZOHN shows bi-directional, linear and fast photoresponse as a function of UV intensity. Electrode materials, light sources, repeatability, durability and flexibility of the prepared CEZOHN were tested and the photocurrent generation mechanism is discussed. The silver nanowire coating used for electrodes on CEZOHN is compatible with a transparent UV sensor. The prepared CEZOHN is flexible, transparent and biocompatible, and hence can be used for flexible and wearable UV sensors.

“…[1] As one of the most rapidly evolving branches of SSL technologies, phosphorconverted white light-emitting diodes (pc-white-LEDs) are gradually replacing conventional lighting sources. [2][3][4][5][6] At the present time, the pc-white-LEDs are fabricated by forming a phosphor layer on an output surface of a near ultraviolet (UV) or blue emitting semiconductor chip. The eventual performance of a pc-white-LEDs device strongly depends on the luminescence properties of the phosphor used.…”

Pr3+-activated barium tungsto-molybdate solid solution phosphor Ba(Mo1−zWz)O4:Pr3+ is successfully fabricated via a facile molten-salt approach. The as-synthesized microcrystal is of truncated octahedron and exhibits deep-red-emitting upon blue light excitation. Powder x-ray diffraction and Raman spectroscopy techniques are utilized to investigate the formation of solid solution phosphor. The luminescence behaviors depend on the resulting composition of the microcrystals with fixed Pr3+-doping concentration, while the host lattices remain in a scheelite structure. The forming solid solution via the substitution of [WO4] for [MoO4] can significantly enhance its luminescence, which may be due to the fact that Ba(Mo1−zWz)O4:Pr3+ owns well-defined facets and uniform morphologies. Owing to its properties of high phase purity, well-defined facets, highly uniform morphologies, exceptional chemical and thermal stabilities, and stronger emission intensity, the resulting solid solution phosphor is expected to find potential applications in phosphor-converted white light-emitting diodes (LEDs).
