Bowl-shaped superstructures of CdSe nanocrystals with the narrow-sized distribution for a high-performance photoswitch
The bowl-shaped CdSe superstructure with a diameter of 1-2 mu m and the thickness of hundreds nanometers was synthesized using Cd(SA)(2) and Se powder in an organic phase. The CdSe nanocrystals for assembling superstructures had a narrow-sized distribution indicated by a sharp emission peak in the photoluminescence (PL) spectrum. Moreover, an organic-inorganic hybrid photoswitch based on CdSe superstructures were fabricated. The device exhibited an on/off switching ratio of similar to 100 with a good cycling stability. The excellent photo-responsible performance illustrates that the superstructures hold a great promise for the application of photoelectric devices. (C) 2015 Elsevier B.V. All rights reserved.
