Abstract

Read online

Femtosecond infrared luminescence has been observed in bulk and nano-structured platinum. Very broad spectra ranging from 0.3 to 1.05 eV are ascribed to hot luminescence within metal like continuous states both in bulk and nano-structured Pt. In addition, an excitation power dependent lifetime was found in Pt nano-structures.
