K2 yellow-band and Rbs orange-band exciter emissions by electron-beam excitation
نویسندگان
چکیده
Amplified spontaneous emissions of the K2 yellow and RbZ orange diffuse bands were observed from e-beam-excited mixtures of K/K, or Rb/Rb, vapor with argon buffer gas. The continuum spectra centered at 574 and 604 nm were attributed to triplet-triplet K, and RbZ 2311,132z bound-free transitions, respectively. The dissociative recombination of Kz or Rbz is discussed as an efficient formation process of upper states by electron-beam pumping.

متن کاملStructure, photoluminescent and cathodoluminescent properties of a rare-earth free red emitting β-Zn3B2O6:Mn2+ phosphor.
A rare-earth free red emitting β-Zn3B2O6:Mn(2+) phosphor was prepared by a solid-state reaction method. The crystal structure, photoluminescent and cathodoluminescent properties of β-Zn3B2O6:Mn(2+) were systematically investigated. The absorption and photoluminescence excitation spectra confirm that β-Zn3B2O6:Mn(2+) matches the UV LED chip. Under UV light and low-voltage electron beam excitatio...
متن کاملDesign and Production of a Pneumatic Moving Exciter for Determination of Vibration Behavior of Structures in Variable Frequencies
Determination and analysis of vibration behavior of structures for at least first few natural frequencies and mode shapes needs several sensors to be connected at different non node points and exciting the structure at one point. Other method for determination of first few mode shapes is to excite several points of the structure at once and sensing the response from one point. Both methods nee...
متن کاملLocal analysis of Eu2+ emission in CaAlSiN3
We have investigated the local luminescence properties of Eu-doped CaAlSiN3 by using low-energy electron beam (e-beam) techniques. The particles yield broad emission centered at 655 nm with a shoulder at higher wavelength under light excitation, and a broad band around 643 nm with a tail at 540 nm under e-beam excitation. Using cathodoluminescence (CL) in a scanning electron microscope (SEM), w...
متن کاملEnhanced tunable narrow-band THz emission from laser-modulated electron beams
Abstract We propose and analyze a scheme to generate enhanced narrow-band terahertz (THz) radiation through down-conversion of the frequency of optical lasers using laser-modulated electron beams. In the scheme the electron beam is first energy modulated by two lasers with wave numbers k1 and k2, respectively. After passing through a dispersion section, the energy modulation is converted to den...
