We report on radiative lifetime measurements of short-lived states in singly ionized platinum by excitation with pico-second laser pulses and subsequent time-resolved detection. The upper levels were populated from metastable ion levels in a laser-generated plasma using radiation in the UV/VUV spectral range. The following lifetimes were obtained: tau(5d(8)(F-3(4))6p(1/2), J = 7/2) = 3.9(3) ns, tau(5d(8)(F-3(4))6p(3/2), J = 9/2) = 3.5(3) ns and tau(5d(8)(F-3(3))6p(1/2), J = 5/2) = 2.6(3) ns. By using relative intensities of the lines found in the literature, oscillator strengths were determined.
