In high-energy nuclear collisions, light nuclei can be regarded as a clusterof baryons and their yields are sensitive to the baryon density fluctuations.Thus, the production of light nuclei can be used to study the QCD phasetransition, at which the baryon density fluctuation will be enhanced. The yieldratio of light nuclei, defined as $N(t)$$\times$$N(p)$/$N^2(d)$, is predictedto be sensitive observable to search for the 1st-order phase transition and/orQCD critical point in heavy-ion collisions. In this paper, we present theenergy and centrality dependence of (anti)deuteron and triton production inAu+Au collisions at $\sqrt{s_{\mathrm{NN}}}$ = 7.7, 11.5, 14.5, 19.6, 27, 39,54.4, 62.4, and 200 GeV measured by the STAR experiment at RHIC. We showbeam-energy dependence for the coalescence parameter, $B_2(d)$ and $B_3(t)$,particle ratios, $d/p$, $t/p$, and $t/d$, and the yield ratio of$N(t)$$\times$$N(p)$/$N^2(d)$. More importantly, non-monotonic energydependence is observed for the yield ratio, $N(t)$$\times$$N(p)$/$N^2(d)$, in0-10\% central Au+Au collisions with a peak around 20-30 GeV. Their physicsimplications on QCD critical point search and change of the equation of statewill be discussed.
