GeSe single‐crystalline microtubes with a rectangular cross section have been fabricated through a facile solution approach. The as‐prepared GeSe microtubes have diameters in the range of 1–2 μm and wall thicknesses of approximately 100–200 nm. Crystal growth along the [010] direction is preferable for the GeSe microtubes. The formation of GeSe microtubes is proposed to originate from an etching effect of the solvent oleylamine. A clear photoresponsive behavior has been found for the as‐synthesized GeSe microtubes. The products were characterized by using powder XRD, energy‐dispersive X‐ray spectroscopy, TEM, SEM, and UV/Vis spectrophotometry.
