| contents | In this article, we analyze the electromagnetic form factors of the vector heavy-light mesons to the pseudoscalar heavy-light mesons in the framework of three-point QCD sum rules, where the contributions of vacuum condensate terms $\langle\overline{q}q\rangle$, $\langle\overline{q}g_{s}σGq\rangle$, $\langle g_{s}^{2}G^{2}\rangle$, $\langle f^{3}G^{3}\rangle$ and $\langle\overline{q}q\rangle\langle g_{s}^{2}G^{2}\rangle$ are considered. With these results, we also obtain the radiative decay widths of the vector heavy-light mesons and then compare our results with those of other collaboration's. The final results about the radiative decay widths are $Γ(D^{*0}\to D^{0}γ)=1.74^{+0.40}_{-0.37}$ keV, $Γ(D^{*+}\to D^{+}γ)=0.17^{+0.08}_{-0.07}$ keV, $Γ(D_{s}^{*}\to D_{s}γ)=0.029^{+0.009}_{-0.008}$ keV, $Γ(B^{*0}\to B^{0}γ)=0.018^{+0.006}_{-0.005}$ keV, $Γ(B^{*+}\to B^{+}γ)=0.015^{+0.007}_{-0.007}$ keV and $Γ(B^{*}_{s}\to B_{s}γ)=0.016^{+0.003}_{-0.005}$ keV. |
