title: Cilostazol determination by the enhancement of the green emission of Tb3+ optical sensor.
abstract: 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).
