英文摘要	Fundamental Research Funds for the Central Universities [2010121053]; Aeronautical Science Foundation of China [2011ZF68004]; Specialized Research Fund for the Doctoral Program of Higher Education [20110121120033]; Science and Technology Program of Fujian Province [2012H0036]; Optical properties of metal atom-doped polycarbosilane (PCS) which originated from sigma-conjugation effect were studied. Al, Dy, Er and Eu were introduced into PCS by one-pot method to yield polyaluminocarbosilane (PACS), polydysprosiumcarbosilane (PDCS), polyerbiumcarbosilane (PErCS) and polyeuropiumcarbosilane (PECS), respectively. Effects of oxidation curing and ultraviolet (UV) radiation on the photoluminescence (PL) properties of the samples were investigated. PL spectra show strong blue light-emissions and the intensity of PCS is enhanced by adding metal atoms. PACS with extended a-conjugation exhibits an obvious PL red-shift, high intensity, high quantum yield and excellent oxidation resistance as compared with those of others. As treated under UV lamp for 3 h in air, PACS retains good UV resistance performance, owing to the AlOx (x = 4, 5, or 6) groups which effectively extend the sigma-conjugation. The obtained results are expected to have important applications in active sources for electroluminescence (EL) devices, especially suitable for blue emission. (C) 2013 Elsevier B.V.
