“…In addition, selenium also holds a high reactivity toward large quantities exploited to convert selenium into other functional materials, such as CdSe, ZnSe, Ag 2 Se, RuSe 2 , Pd17Se15, Pt etc [5][6][7][8][9][10][11]. Recently, many methods reported in literature were used to obtain diverse nano-or microstructures of Se, such as laser ablation using selenium powders [12], sonochemical assistance approach [13], solution-mediated transformation [14][15][16][17], hydrothermal method [18], chemical vapor deposit (CVD) [19][20][21], and photoinduced method [22,23]. However, in order to obtain polydispersed nano-or microstructures, these reactions have to be assisted by special conditions such as high temperature and/or pressures, sonochemical process or invert gas surrounding.…”
