Abstract In the present work, we adopt a relativistic constituent quark model to depict the charmed strange meson spectroscopy, in which $$D_{s0}(2317)$$ Ds0(2317) and $$D_{s1}(2460)$$ Ds1(2460) are considered as the $$1^3P_0$$ 13P0 and $$1P_1^\prime $$ 1P1′ charmed strange mesons, respectively. By using the wave function obtained from the relativistic quark model, we further investigate the electric transitions between charmed strange mesons. We find the long wave length approximation is reasonable for the charmed strange meson radiative decay by comparing the results with different approximations. The estimated partial widths are all safely under the upper limits of the experimental data. Moreover, we find the branching ratio of $$D_{s1}(2536) \rightarrow D_s^*\gamma /D_s \gamma $$ Ds1(2536)→Ds∗γ/Dsγ are large enough to be detected, which could be searched by further experiments in Belle II and LHCb.
