Buch The Chemistry of Artificial Lighting Devices: Lamps, Phosphors and Cathode Ray Tubes (ISSN Book 17) (English Edition)

Beschreibung The Chemistry of Artificial Lighting Devices: Lamps, Phosphors and Cathode Ray Tubes (ISSN Book 17) (English Edition)

Both the early use of artificial lighting and current manufacturing methods concerning incandescent and fluorescent lamps are covered in this book. The protocols for manufacture of fluorescent lamp phosphors and those used in cathode ray tubes are also treated in some detail. This text surveys the amazing, vast array of artificial lighting devices known to date in terms of how they arose and are, or have been used by mankind.A complete description of the formulations and methodology for manufacturing all known phosphors is given. The book will serve as a repository of such phosphor manufacturing methods, including that of cathode ray tube phosphors. Methods of manufacture of lamp parts are also presented, including that of tungsten wire. The original approaches used are described as well as improvements in technology. These will serve as comparative methods for present day manufacture of these components. A history of the lamp industry is presented. Several methods are given which may serve as a source for further work in the lamp industry. Some of the earliest work has been applied in the laser industry to develop new types of discharge lasers. These include nitrogen-gas lasers and the rare gas (excimer) lasers. Previous work on lamps may also be applied in the development of new types of lasers.

Lab #7: Analyzing Light: The Spectroscope - Chemistry Land ~ TVs and Computer monitors make us see yellow by lighting up red and green phosphors (pixels). You might see a little bit of blue in your spectrum, but it's not normally there or needed for bright yellow. Our eyes see lights but can't really tell what kind of light it is. For example, in the picture, we aren't sure which rooms are lit by fluorescent lights or incandescent lights (light bulbs .

Fluorescent lamp - Wikipedia ~ 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 .

Mercury-vapor lamp - Wikipedia ~ A mercury-vapor lamp is a gas-discharge lamp that uses an electric arc through vaporized mercury to produce light.The arc discharge is generally confined to a small fused quartz arc tube mounted within a larger borosilicate glass bulb. The outer bulb may be clear or coated with a phosphor; in either case, the outer bulb provides thermal insulation, protection from the ultraviolet radiation the .

Phosphorescence - Wikipedia ~ Phosphorescence is a type of photoluminescence related to fluorescence.Unlike fluorescence, a phosphorescent material does not immediately re-emit the radiation it absorbs. The slower time scales of the re-emission are associated with "forbidden" energy state transitions in quantum mechanics.As these transitions occur very slowly in certain materials, absorbed radiation is re-emitted at a .

Yttrium aluminium garnet - Wikipedia ~ Yttrium aluminium garnet (YAG, Y 3 Al 5 O 12) is a synthetic crystalline material of the garnet group. It is a cubic yttrium aluminium oxide phase, with other examples being YAlO 3 (YAP) in a hexagonal or an orthorhombic, perovskite-like form, and the monoclinic Y 4 Al 2 O 9 (YAM).. YAG, like garnet and sapphire, has no uses as a laser medium when pure.However, after being doped with an .

Sir William Crookes / British chemist / Britannica ~ Sir William Crookes, (born June 17, 1832, London, Eng.—died April 4, 1919, London), British chemist and physicist noted for his discovery of the element thallium and for his cathode-ray studies, fundamental in the development of atomic physics.. After studying at the Royal College of Chemistry, London, Crookes became superintendent of the meteorological department at Radcliffe Observatory .

Types of Lights - National Optical Astronomy Observatory ~ Types of Lights Metal Halide: Metal halide lamps are commonly used in streetlights, parking lot lights, and stadium lights. They are very bright and contribute to a lot of light pollution. They are fairly efficient. They produce very white light and have good color rendition, meaning that objects under these lights look their true color. CRI: 85-94 Wattage 250 400 1000 Lumens 22,000 36,000 .

How Television Works / HowStuffWorks ~ A few TVs in use today rely on a device known as the cathode ray tube, or CRT, to display their images. . The radiation might be ultraviolet light or a beam of electrons. Any fluorescent color is really a phosphor -- fluorescent colors absorb invisible ultraviolet light and emit visible light at a characteristic color. In a CRT, phosphor coats the inside of the screen. When the electron beam .

Augmented reality - Wikipedia ~ Augmented reality (AR) is an interactive experience of a real-world environment where the objects that reside in the real world are enhanced by computer-generated perceptual information, sometimes across multiple sensory modalities, including visual, auditory, haptic, somatosensory and olfactory. AR can be defined as a system that fulfills three basic features: a combination of real and .
