We report an optical investigation of single phase icosahedral Al59B3Cu25.5Fe12.5. The optical conductivity presents a striking depression at low frequencies and a prominent peak at 3 104 cm−1.A phenomenological analysis of the conductivity allows us to correlate the high energy excitations to a mechanism of electron hopping.
