With the world largest data sample taken at psi(3770) peak with the BESIII detector at the BEPCII e+e- collider, the D+ purely leptonic and D0 semi-leptonic decays are studied. We present the preliminary branching fraction measurements of D+ -> mu nu, D0 -> K- e+ nu and D0 -> pi- e+ nu. We extract pseudoscalar decay constant of f_D using D+ purely leptonic decays and the hadronic form factors using the D0 semi-leptonic decays.
