The efficiency of excited-state interaction between Tb(3+) and the industrial product Cilostazol (CIL) has been studied in different solvents. High luminescence intensity peak at 545 nm of terbium complex in acetonitrile was obtained. The photophysical properties of the green emissive Tb(3+) complex have been elucidated, the terbium was used as optical sensor for the assessment of CIL in the pharmaceutical tablets and body fluids at pH 3.1 and λ(ex) = 320 nm with a concentration range 1.0 × 10(-9)-1.0 × 10(-6) mol L(-1) of CIL, correlation coefficient of 0.998 and detection limit of 7.5 × 10(-10) mol L(-1).
研究了铽（Tb(3+)）与工业产品西洛他唑（CIL）在不同溶剂中激发态相互作用的效率。在乙腈中获得了铽配合物在 545nm 处的强荧光强度峰。阐明了绿色发射 Tb(3+)配合物的光物理性质，铽被用作光学传感器，用于在 pH 3.1 和 λ(ex) = 320nm 下评估药物片剂和体液中的 CIL，CIL 的浓度范围为 1.0×10(-9)-1.0×10(-6)mol L(-1)，相关系数为 0.998，检测限为 7.5×10(-10)mol L(-1)。
