Tin selenides SnSe X (x=1,2) were synthesized from tin and selenium powder precursors by high-energy milling in the planetary ball mill Pulverisette 6 (Fritsch, Germany). The objective of this study was to prepare nanocrystalline SnSe and SnSe 2 by mechanochemical synthesis and to evaluate their crystalline structure, morphology, physico-chemical and optical properties. The methodology involved high-energy milling of tin and selenium powders, observing the formation of the orthorhombic tin selenide SnSe and the hexagonal tin diselenide SnSe 2 phases after 4 min and 5 min of milling, respectively. Results indicated that the specific surface area of both selenides increased with prolonged mechanical synthesis, with particle size distribution analysis revealing agglomerated selenide particles comprising numerous idiomorphic tin selenide crystals ranging from 2 to over 100 nm in diameter. Additionally, UV-Vis spectrophotometry confirmed that the synthesized tin selenide particles do not exhibit quantum dot behavior.
