Van der Waals (vdW) heterojunctions based on two-dimensional materials have attracted great attention in emerging photoelectronics. However, the low-efficiency growth of single crystals significantly limits the practical applications of vdW heterojunctions. Here, we report a macro SnSe/SnSe2 heterojunction assembled by

Nanocrystals of phase-pure tin(II) selenide (SnSe) were synthesized via a solution-phase route employing stoichiometric amounts of di-tert-butyl diselenide as a novel and facile selenium source. The direct band gap of the resulting nanocrystals (E(g) = 1.71 eV) is significantly blue-shifted
