摘要：

The authors experimentally observed the superluminal propagation at negative group velocity in C-60 polymethyl methacrylate (PMMA) firstly. The largest time advancement of 7.61 ms was obtained at 1 mg/cm(3) of sample concentration, the corresponding group velocity was -0.657 m/s. Fast light in C60 PMMA offers several advantages over liquids or vapors for a variety of possible applications: (i) easy for experimental measurement and practical applications (ii) easy for manufacture, (iii) sample concentration is another convenient parameter to vary the signal delay.
