  In the present work, we study the radiative decay of newly observed
$\Xi_c(2923)^0$ based on the successful explanation that $\Xi_c(2923)^0$ is an
$S$-wave $D\Lambda-D\Sigma$ molecular state in our previous
study~\cite{Zhu:2020jke}. The radiative decay width of $D\Lambda-D\Sigma$
molecular state into $\Xi_c^0\gamma$ final state through hadronic loops are
evaluated using effective Lagrangians. We find that decay width
$\Xi_c(2923)^0\to\Xi_c^0\gamma$ and $\Xi_c(2923)^0\to\Xi_c^{'0}\gamma$ is
evaluated to be approximately 1.23-11.66 KeV and 0.30-3.71 KeV, respectively.
These are different from the results~\cite{Wang:2020gkn,Bijker:2020tns} that
obtained by assuming $\Xi_c(2923)^0$ may be conventional charmed baryon. If
measurements are in future experimental, these differences will be very useful
to help us to test various interpretations of $\Xi_c(2923)^0$.
