Silicon-nanowire (Si-NW) array, prepared by an electroless chemical-etching method, shows excellent optical antireflection property over a wide spectral bandwidth. The influence of the wire length on and solar cell performance were studied for both Si-NW array cells planar cells. reflectance NWs is almost invariable much lower than that but best. Results show strongly affected some other factors such as surface passivation electrode-contact property.
We have demonstrated an organic light-emitting diode based on molybdenum oxide (MoOx) doped 4,4′,4″-tris(3-methylphenylphenylamino)triphenylamine (m-MTDATA) as a p-type doping hole injection layer. The tris-(8-hydroxyquinoline) aluminum (Alq3)-based diodes show high brightness at very low operating voltage, 100cd∕m2 3.2V and 1000cd∕m2 4.4V, corresponding to turn-on voltage of 2.4V. Such improved properties are attributed the formation charge transfer complex produced by MoOx into m-MTDATA,...

Five simian virus 40 (SV40)-hepatocyte cell lines were examined for tumorigenicity and the effect of in vitro passage on expression four liver-specific genes (albumin, transferrin, alpha 1-antitrypsin, phosphoenolpyruvate carboxykinase), two oncogenes (c-Ha-ras c-raf), associated with hepatocarcinogenesis (alpha-fetoprotein placental-type glutathione-S-transferase). At low (12 to 22), all five expressed at levels similar those liver not tumorigenic or weakly tumorigenic. high (33 61), formed...
Random speckle patterns contain valuable information about the incident light. Researchers have successfully constructed spectrometers and wavemeters by utilizing speckles generated inter-mode interferences of a multimode fiber (MMF). However, cameras were often employed to record data in previous reports. The camera's high cost (especially near-infrared range), large size, low response speed limit applications optical communications, metrology, sensing. A seven-core (SCF) was fused with an...
High performance radial p-n junction solar cells based on silicon nanopillar array were synthesized from p-type substrates and compared with planar cell. These exhibited considerable higher short-circuit current, due to their unique carriers' decoupling mechanism. After the electrode enhancement via light induced plating, a best efficiency of near 12% was achieved for cell, which is better than control
In the case of silicon (Si) nanowire (NW)-array-textured solar cells, electrode-contact enhancement has been achieved using a simple and convenient double-step diffusion process to form highly doped N+ region at tips Si-NW array. The series resistance can be effectively reduced, leading an increase in short-circuit current density cell.

In this study, we investigated an absorber based on a center-aligned tandem nanopillar array for ultra-broadband solar energy harvesting theoretically. A high-efficiency, omnidirectional was obtained by introducing the embedded in Al2O3 dielectric layer. The multi-coupling modes at different wavelengths were interpreted. strong absorption can be adjusted changing radii and heights of nanopillars. According to simulation results, average absorptance exceeded 94% wavelength range from 300 nm...
For speckle pattern-based wavemeters or spectrometers, the intermodal and chromatic dispersion of diffusion waveguide are key factors in determining wavelength resolution. In this study, we propose a new mechanism to modulate fiber speckles aside from related effect. The polarization modulation is introduced rectangular core (RCF) by using an in-line rotator (IPR). IPR can rotate angle at different wavelengths. Interestingly, it observed that modulated patterns appear periodically similar,...
Although organic light-emitting devices (OLEDs) can achieve an internal quantum efficiency (QE) of 100%, their external QE remains limited to less than 40% due low outcoupling (OCE). The distribution excitons is a critical factor in determining OLED OCE, as it affects the coupling surface plasmon polaritons. Therefore, investigating exciton through experiments crucial optimize device structure and enhance OCE. In this study, we propose probe method analyze by inserting ultrathin (∼0.1 nm)...
The interaction between magnetic quantum emitters and the local electromagnetic environment is a promising method to manipulate spontaneous emission. However, it severely limited by weak interactions component of light natural materials.

Based on states, radiative power effectively suppressed significant coupling emitter nonamer,...
The organic compound, 2,9-dimethyl-4,7-diphenyl-1,10-phenanthroline (BCP) is used as a light outcoupling layer in top-emitting light-emitting devices with tris(8-hydroxyquinoline) aluminum emission layer. It found that, addition to the improvement of electroluminescent (EL) intensity and luminous efficiency factor 1.6, BCP capping causes blueshift EL spectra larger full width at half maximum (FWHM). A FWHM 50nm attributed reduction cathode reflectivity. In meantime, caused by increase...
