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 10 2− and B 12 H 12 2− compounds displayed photoluminescence in the ultraviolet (emission λ max ≈ 350 nm) that was not visible to the human eye,...

Summary: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 10 2− and B 12 H 12 2− 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.
