摘要：

Single-phase, near granular shaped quaternary chalcopyrite Cu(In1-xAlx)Se-2 nanocrystals (0 <= x <= 0.5) were synthesized by a facile, air pressure hot-injection process using triethylenetetramine(TETA)-assisted triethylene glycol solution, CuCl2 center dot 2H(2)O, InCl3 center dot 4H(2)O, AlCl3 center dot 6H(2)O and Se powder as precursors, polyvinylpyrrolidone as dispersant, at solution temperature 270 degrees C. The TETA-assisted role, the optimum TETA added amount and the effects of reaction solution temperatures were investigated based on X-ray diffraction, energy dispersive X-ray analyses, transmission electron microscopy, high resolution transmission electron microscopy and selected area electron diffraction. The band gap energy tuning with varying In/Al atomic ratios in feeding solutions was characterized by X-ray diffraction, inductively coupled plasma mass spectrum, Raman spectroscopy and UV-vis-NIR absorption.
