Abstract
The photoluminescent properties of selected metal closo-boranes have been assessed. Group 3 elements Sc, Y, and La as well as Li, Na, and Eu-based B 10 H 102- and B 12 H 122- compounds displayed photoluminescence in the ultraviolet (emission λ max ≈ 350 nm) that was not visible to the human eye, in contrast to previous reports. We attribute these earlier results to arachno-borane impurities, which are more readily observed due to their longer wavelength emission spectra.
