摘要	A green and economical hydrothermal route was developed to synthesize uniform trigonal selenium (t-Se) microspheres with an average diameter of 1 mu m by using ascorbic acid (Vc) as a mild reducing agent and Se powder as the selenium source. The as-prepared products were investigated by X-ray diffraction (XRD), scanning electron microscopy (SEM) and transmission electron microscopy (TEM). Experimental results reveal that the morphology of t-Se microspheres is strongly dependent on the reaction conditions such as the amount of Vc, reaction temperature and reaction time. The tentative growth mechanism of t-Se microspheres is also discussed in this letter. Photoluminescence spectrum indicates that the t-Se microspheres with an average diameter of 1 mu m exhibit a strong red-emitting peak at 675 nm. (C) 2013 Elsevier B.V. All rights reserved.
