Hace 4 días · The absorbance spectra of F8T2-sorted sc-SWCNT inks were acquired using a UV–Vis−NIR spectrophotometer (Lambda 750, Perkin Elmer). The surface morphologies of the sc-SWCNT networks were conducted by Scanning electron microscopy (SEM, Nova NanoSEM450).
Hace 4 días · Optical properties were analyzed by UV–Vis spectroscopy (Lambda 365 Perkin Elmer) with double beam of spectrum range (190–1100 nm) and a photoluminescence device (Fluoro Mate FS-spectrometer) with excitation wavelength of 320 nm.
Hace 1 día · The adsorption spectra of samples were recorded with a Lambda 750 Perkin Elmer UV/Vis/NIR spectrophotometer in the range 300–800 nm (PerkinElmer, Waltham, MA, USA). ... After that, the membranes were removed from the tubes, and the liquid was examined under UV light (365 nm) to verify the absence of any luminescence. Indeed, ...
Hace 3 días · El propósito principal del estudio no fue determinar el "color del universo", sino llevar a cabo un análisis espectral de diversas galaxias con el fin de investigar la formación de estrellas.
Hace 5 días · In physics, Planck's law (also Planck radiation law [1] : 1305 ) describes the spectral density of electromagnetic radiation emitted by a black body in thermal equilibrium at a given temperature T, when there is no net flow of matter or energy between the body and its environment. [2]
