SPATIALLY CONFINED HIGH-TEMPERATURE BLACKBODY RADIATION FROM C-60 FILMS

Under green laser irradiation, intense white light emission was observ ed from C-60 films into which Si thin layers were intercalated by sput tering. The emission spectra extending from the visible to mid-infrare d region fit quite well with the Planck's formula for blackbody radiat ion, yielding surprisingly high blackbody temperatures of 1100-2140 K. Optical micrographs, AFM, microscopic FT-IR, and microscopic Raman me asurements show that the emission comes from small domains scattered o ver C-60 films that are morphologically and chemically modified to som e extent by the combined effects of the sputtering process and laser i rradiation.
