A displaced thermal state (DTS) is first introduced by Jeong et al. [Phys. Rev. Lett. 97, 100401 (2006)] and its superpositions can be used in transfer of nonclassicality. In this paper, the analytical evolution law of the DTS exposed to dissipative environments is obtained according to the Kraus operator for amplitude damping. The results manifestly show that, after undergoing the amplitude damping, the initial DTSs still keep mixed and thermal with the exponential decay due to amplitude damping. An appealing feature is that the entropy evolution in this process completely depends on the mixedness.
