WebFigure 2-1 shows the excitation and emission spectra of a yellow-green fluorescent dye (Molecular Probes, Inc.). The excitation spectra is determined by measuring the emission intensity at a fixed wavelength, in this case 506 nm, while varying the excitation wavelength. The emission spectra is determined by measuring the variation in emission ... A fluorescent lamp, or fluorescent tube, is a low-pressure mercury-vapor gas-discharge lamp that uses fluorescence to produce visible light. An electric current in the gas excites mercury vapor, which produces short-wave ultraviolet light that then causes a phosphor coating on the inside of the lamp to glow. A fluorescent lamp converts electrical energy into useful light much more efficiently than an i… howard abraham motors lurgan kia

WebFluorescence is a type of radiative emission that occurs when a molecule absorbs energy at a wavelength where it has a transition dipole moment. The excitation energy provided to the molecule at the ground state promotes photons to an excited singlet state, where they then decay to the lowest vibrational energy level of this excited singlet state. WebIn contrast to a fluorescent bulb or a gas tube, an incandescent lamp emits a purely continuous Planck spectrum. As shown in Figure 2.6, an absorption spectrum is created when a continuous source is viewed (head on) through a low-density cloud, and an emission spectrum is created when a source of energy is exciting a low-density cloud.
