“…Among them, wet chemical precipitation synthesis is widely applied as it is simple and controllable. [26][27][28] A notable fact is that although syntheses are performed under similar conditions in the literature, even nominally identical protocols create entirely different product nanostructures, from zero-dimensional (nanoparticles) to three-dimensional (nanoflowers or spherical structures), which induces different final properties. [29][30][31] Synthesis temperature has been identified as having a strong influence on the final nanostructures and a small number of previous studies has reported that a synthesis temperature increase leads to the growth of nanoparticles, which become more crystalline and have a narrower band gap (E g ).…”
