摘　　要：Ge-based selenides have attracted extensive attention as promising candidates for future optoelectronic applications.Despite great progress has been achieved,the controlled synthesis of GeSe2and GeSe nanostructures and understanding the relative growth mechanisms of them are still lacking.Herein,monodispersed GeSe_(2) nanoflowers with a diameter of~4μm and highly uniform GeSe nanoparticles with a lateral size of~100 nm are presented by using a colloidal synthetic method.It is found that borane tert-butylamine complex(TBAB)plays an important role in determining the Ge-Se crystal phases due to its moderately reducibility.Furthermore,the coexistence of GeSe_(2) and GeSe phases can also be acquired by precisely controlling the amount of TBAB.In brief,this work provides both new insights of the phase control of Gebased selenides by liquid-phase method and a practical means of producing well-controlled germanium selenide nanostructures.
