We search for the radiative decays D+ → γρ+ and D+ → γK*+ using 20.3 fb−1 of e+e− annihilation data collected at the center-of-mass energy s = 3.773 GeV by the BESIII detector operating at the BEPCII collider. No significant signals are observed, and the upper limits on the branching fractions of D+→ γρ+ and D+→ γK*+ at 90% confidence level are set to be 1.3 × 10−5 and 1.8 × 10−5, respectively.
