摘要：
The modification of C-60-film structure under laser and X-ray irradiation has been investigated. The wide spectral and dose ranges of irradiation have been applied: from visible light to hard X-ray, and from low to high intensity, when the optical nonlinear effects appear. The structure changes (including the polymerization) manifesting close to nonlinear threshold have been found. They have exhibited the nonreversible effect contribution to the nonlinear parameters of initial C-60-films. The dependence Of C-60-film structure modification on irradiation wavelength has been demonstrated by the photoluminescence and transmission spectral measurements, the solubility controlling, and data of X-ray diffractometery as well. The contribution of X-ray and a secondary electron flow to polymerization of the C-60-film has been determined [1]. The information about C-60-film modification may be used for optical limiting devices and for the development of UV and X-ray resists.
