本文报道了磷光有机金属配合物三（2-苯基吡啶）-铱(Ir（ppy)(3)）的单分子研究结果。单分子发射强度表现出广泛的多组分分布。以特定强度发光的分子的光漂白次数呈指数分布。平均光漂白时间的倒数与发射强度的关系揭示了低强度下的线性关系和高强度下更复杂的行为。在Ir(ppy)(3)上得到的结果与荧光标记二乙基氧碳菁的结果进行了比较。(C) 2004 Elsevier B.V.版权所有
We report results of single Molecule study of phosphorescent organometallic complex, tris(2-phenylpyridine)-iridium (Ir(ppy)(3)). Single molecule emission intensities show a wide multi-component distribution. Photobleaching times of molecules emitting with particular intensity are exponentially distributed. The dependence of the inverse of the mean photobleaching time on the emission intensity reveals linear dependence for lower intensities and more complex behavior for higher intensities. The results obtained on Ir(ppy)(3) are compared with those of a fluorescent label, diethyloxacarbocyanine. (C) 2004 Elsevier B.V. All rights reserved.
