[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 ...
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."
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 ...
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 ...
The neon trimer is shaped approximately like an equilateral triangle with sides 3.3 Å long. However the shape is floppy and isosceles triangle shapes are also common. The first excited state of the neon trimer is 2 meV above the ground state. The neon tetramer takes the form of a tetrahedron with sides around 3.2 Å. [4]
Pearson-Anson oscillator circuit. The Pearson–Anson effect, discovered in 1922 by Stephen Oswald Pearson [1] and Horatio Saint George Anson, [2] [3] is the phenomenon of an oscillating electric voltage produced by a neon bulb connected across a capacitor, when a direct current is applied through a resistor.

Later bulbs called C 7 + 1 ⁄ 2, have diameters of seven and a half 1/8th inches (15 ⁄ 16 in, or 24 mm) using an E12 candelabra base; however, these have a blunt shape (and should therefore be called B 7 + 1 ⁄ 2, or B24). 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 ...
