Cu2PO4OH: Controlled synthesis of various architectures and morphology-dependent 808 nm laser-driven photothermal performance

Various architectures of Cu 2 PO 4 OH including multibranches-like, rose-like, rod-like and brick-like were synthesized through a facile solvothermal route, employing different kinds of alcohols as solvents. It was found that the types of the alcohols, the ratios of alcohols to water, and the presence of PEG 2000 played key roles in the aspect of adjusting the growth of Cu 2 PO 4 OH architectures. All of the as-obtained products showed strong and wide absorption in the range of 600–1500 nm. Under the irradiation of a continuous 808 nm laser, the materials exhibited morphology-dependent photothermal performance. The present study not only develops a new strategy to synthesize Cu 2 PO 4 OH with various architectures but also provides a promising near-infrared (NIR) light-driven photothermal agent.
