Abstract

The phosphorescence of C60 in Kr and Xe matrixes is reported. It consists of a progression of bands of monotonically decreasing intensity which belong to the hg(1) mode but in Xe weaker contributions from the t1u, t2u, hu and gu modes are also present. In Xe matrixes, the phosphorescence stems from a distribution of sites extending up to 150 cm-1 to the red of the main and most prominent one having its origin at 12714 cm-1. The phosphorescence lifetime is 16 +- 1 ms in Xe and 60 +- 5 ms in Kr. The phosphorescence is attributed to the 3T2g state, whose gas phase energy the authors est. to be 12925 +- 10 cm-1 from the gas-to-matrix shift. [on SciFinder (R)]

Xenon

Xenon is a chemical element with the symbol Xe and atomic number 54. It is a dense, colorless, odorless noble gas found in Earth's atmosphere in trace amounts. Although generally unreactive, it can undergo a few chemical reactions such as the formation of xenon hexafluoroplatinate, the first noble gas compound to be synthesized. Xenon is used in flash lamps and arc lamps, and as a general anesthetic. The first excimer laser design used a xenon dimer molecule (Xe2) as the lasing medium, and the earliest laser designs used xenon flash lamps as pumps.

Phosphorescence

Phosphorescence is a type of photoluminescence related to fluorescence. When exposed to light (radiation) of a shorter wavelength, a phosphorescent substance will glow, absorbing the light and reemitting it at a longer wavelength. Unlike fluorescence, a phosphorescent material does not immediately reemit the radiation it absorbs. Instead, a phosphorescent material absorbs some of the radiation energy and reemits it for a much longer time after the radiation source is removed.

Noble gas

The noble gases (historically also the inert gases; sometimes referred to as aerogens) make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity. The six naturally occurring noble gases are helium (He), neon (Ne), argon (Ar), krypton (Kr), xenon (Xe), and the radioactive radon (Rn). Oganesson (Og) is a synthetically produced highly radioactive element.
