Photochemical self-assembly synthesis and characterization of CdSe dendrites

Wurtzite CdSe dendrites were synthesized by an UV-irradiation photochemical reaction. The products were characterized by X-ray powder diffraction, transmission electron microscope, X-ray photoelectron spectroscopy, UV–vis spectra, Raman spectroscopy and photoluminescence spectroscopy. The electron microscope images showed that most of the dendrites had a width of around 1 μm with lengths of up to 3 μm. The formation of wurtzite CdSe dendrites can be explained as a self-assembly growth from early-formed particles under reduction conditions.
