摘要

A facile colloidal approach was developed to prepare cubic Cu_2(Ge_(1-x),Sn_x)(S_(3-y),Se_y) nanocrystals (NCs) (0 ≤ x ≤ 1, 0 ≤ y ≤ 3). The band gaps of the NCs can be tuned in the range of 1.35-2.45 eV by varying the chemical compositions, and the NCs display promising applications in solar energy utilization.
