[15] Following neon's discovery, neon tubes were used as scientific instruments and novelties. [16] A sign created by Perley G. Nutting and displaying the word "neon" may have been shown at the Louisiana Purchase Exposition of 1904, although this claim has been disputed; [ 17 ] in any event, the scarcity of neon would have precluded the ...
Neon lights were named for neon, a noble gas which gives off a popular orange light, but other gases and chemicals called phosphors are used to produce other colors, such as hydrogen (purple-red), helium (yellow or pink), carbon dioxide (white), and mercury (blue). Neon tubes can be fabricated in curving artistic shapes, to form letters or ...
A General Electric NE-34 glow lamp, manufactured circa 1930. Neon was discovered in 1898 by William Ramsay and Morris Travers.The characteristic, brilliant red color that is emitted by gaseous neon when excited electrically was noted immediately; Travers later wrote, "the blaze of crimson light from the tube told its own story and was a sight to dwell upon and never forget."
1910 Georges Claude demonstrates neon lighting at the Paris Motor Show. 1912 Charles P. Steinmetz invents the metal-halide lamp. [13] 1913 Irving Langmuir discovers that inert gas could double the luminous efficacy of incandescent lightbulbs. 1917 Burnie Lee Benbow patents the coiled coil filament. 1920 Arthur Compton invents the sodium-vapor ...
Neon's polarisability of 0.395 Å 3 is the second lowest of any element (only helium's is more extreme). Low polarisability means there will be little tendency to link to other atoms. [1] Neon has a Lewis basicity or proton affinity of 2.06 eV. [2] Neon is theoretically less reactive than helium, making it the least reactive of all the elements ...
Mixing metric and English units, there are also now G30 globes which are 30 mm (1 + 3 ⁄ 16 in, or G 9 + 1 ⁄ 2) in diameter using these sockets. These are still used for the classic look or even retro style, and use about five watts each. Older bulbs drew 7 + 1 ⁄ 2 watts of power, and were reduced to save power.
Sodium vapor lamps used in streetlights "Neon" signs, which use both visible light discharge from neon and other gases and phosphor excitation from ultraviolet light; Mercury vapor lamps; Mass spectrometers; Cathode-ray tubes, employed in the oscilloscope and later in television sets, radar, and computer display devices
