Solution: a visible light and an ultraviolet ray absorber having a short wavelength region characterized by an anthracene compound represented by formula (1). R represents an alkyl group which can contain oxygen atoms having from 1 to 12 carbon atoms, and X and Y represent alkyl groups having ...
1) Whole visible light wavelength range 全波段可见光2) visible region 可见光全波段 1. The lyouropic liquid crystal was prepared by rotary-evaporating 1% solution of sulfonated IBRSN and ISGG(MRSN/MGG=2/1,w/w),then coated on the glass slide,and such mixed sulfonated dye polarize film ...
After screening various photoinitiators, we identified DPTBP, the structure of which is shown in Fig.1b. DPTBP satisfies the three requirements previously mentioned. The UV–Vis absorption spectrum of DPTBP shows that the majority of light absorption was detected in the UV wavelength region from ...
region of the entire spectrum, is produced by hot, incandescent matter and fromelectrical dischargesthrough gases. It is usually accompanied by infrared and sometimes byultraviolet radiation. The longest of the visible wavelengths is the red light and as the wavelength shortens the “colours of the...
light-field sensor. The thickness of surface structures is 0.6 mm and the wavelength of the laser is 405 nm.f, Absorption contrast image of two commercial PMMA rods (1 mm and 2 mm diameters; 50 kV X-rays) and the corresponding phase-gradient map measured using the 3D light...
The prominent MoS2 Raman modes were observed at around 550 nm wavelength region for all MoS2TFs samples. Not only that, the broad PL spectra profile and non-obvious excitonic features (A and B exciton peak) of the MoS2TFs are similar to bulk crystal MoS2 (Figure 7b). The PL signal of ...
The RISE process is to compensate the light non-overlap zones based on the ratio of the other illuminated region. The RISE process is as shown in Equation (3), 𝑅𝑆𝑆𝑒𝑛ℎ𝑎𝑛𝑐𝑒𝑑=𝑅𝑆𝑆𝑜𝑟𝑖𝑔𝑖𝑛𝑎𝑙+(ℎ𝑠𝑡𝑑−ℎ𝑡arg𝑒𝑡)tan...
Humans see light at the lower end of the visible spectrum, having a longer wavelength, about 740 nm, as red; we perceive light in the middle of the spectrum as green; and see light at the upper end of the spectrum, with a wavelength of about 380 nm, as violet. All other colors ...
Wavelength-division multiplexed optical interconnects using monolithic wavelength-graded VCSEL and resonant photodetector arrays Monolithic wavelength-graded vertical-cavity surface- emitting laser (VCSEL) and wavelength-selective resonance enhanced photodetector (REPD) arrays have b...

We demonstrate the blue light generated in high-Δ photonic crystal fibers (PCFs). A femtosecond Yb-doped fiber laser, operating at 1039nm, is used to pump a GeO-doped PCF in the largely anomalous group velocity dispersion (GVD) region. The emitted radiation covers 418.6–544.6nm with 5dB ...
