Book Description
Time-resolved spectra from electrically pulsed zinc vapor discharges show a dominance of peak power emission in the blue-green. There is a good potential of developing a convenient, inexpensive source for underwater systems, as kilowatts of peak power were obtained in this spectral region from a short arc configuration. The dominant transitions were at a triplet (4680, 4722, and 4810 A) in ZnI and at a doublet (4912 and 4924 A) in ZnII. Gain measurements show that in a pulsed electric discharge of pure zinc the population of the ground state of the doublet was unexpectedly large. Oscillations at these wavelengths by electron collisional excitation do not occur. This was verified experimentally. Models are proposed for anomalous population densities of excited states and for the above dominance of fluorescent spectra.

Zinc Oxide Materials for Electronic and Optoelectronic Device Applications
Author: Cole W. LittonPublisher: John Wiley & Sons
ISBN: 0470519711
Category : Technology & Engineering
Languages : en
Pages : 403
Book Description
Zinc Oxide (ZnO) powder has been widely used as a white paint pigment and industrial processing chemical for nearly 150 years. However, following a rediscovery of ZnO and its potential applications in the 1950s, science and industry alike began to realize that ZnO had many interesting novel properties that were worthy of further investigation. ZnO is a leading candidate for the next generation of electronics, and its biocompatibility makes it viable for medical devices. This book covers recent advances including crystal growth, processing and doping and also discusses the problems and issues that seem to be impeding the commercialization of devices. Topics include: Energy band structure and spintronics Fundamental optical and electronic properties Electronic contacts of ZnO Growth of ZnO crystals and substrates Ultraviolet photodetectors ZnO quantum wells Zinc Oxide Materials for Electronic and Optoelectronic Device Applications is ideal for university, government, and industrial research and development laboratories, particularly those engaged in ZnO and related materials research.
Laser Isotope Separation in Atomic Vapor

Book Description
Written by leading Russian scientists, including Nobel laureate, A.M. Prokhorov (1916-2002), this first book on this important technology allows an understanding of the physics of atomic vapor laser isotope separation and new photochemical methods of laser isotope separation. One entire chapter is devoted to chemical reactions of atoms in excited states, while further chapters deal with the separation of isotopes by one photon isotope-selective and coherent isotope-selective two photon excitation of atoms. A final chapter looks at the prospects for the industrial production of isotope products by laser isotope separation. The whole is rounded off by six appendices.
