The radiation decay of a two-level atom could be inhibited within structured environments even under longtime evolution. We investigate the stabilized quantum coherence of composite systems undergoing local dissipation and exploit it further as a resource for remote state preparation. We focus on outputs of quantum states with solely quantum discord (i.e., without entanglement) and demonstrate that they could be resulted from various initial states providing specific spectral structure of the reservoir. In detail, we elaborate the behavior of stabilized quantum discord and the corresponding fidelity for remote state preparation in connection with structural spectra of Ohmic class reservoir and of photonic band gap mediums.
