Synthesis and characterization of wurtzite ZnSe one-dimensional nanocrystals through molecular precursor decomposition by solvothermal method

Wurtzite ZnSe 1D nanowires with 10–100 nm in diameter and up to several micrometers in length were successfully synthesized through molecular precursor decomposition by solvothermal method at 220 °C for 15 h, where hydrazine served as not only reduction agent but also complexing agent and molecular template. The products were characterized by XRD, FTIR, TG-DSC, TEM (SAED), UV–vis and photoluminescence (PL) spectrum. In-depth investigation indicated that the as-prepared 1D nanocrystals had [0 0 1] preferential orientation and showed a room-temperature photoluminescent property. The possible growth mechanism was also proposed.
