Fabrication of CdSe nanocrystals using porous anodic alumina and their optical properties

Preparation and photoelectric properties of cadmium sulfide quantum dots

“…At present, there are several methods to prepare QDs, such as organic metal synthesis, template, hydrothermal, co-precipitation, sol-gel and wet chemical methods. [11][12][13][14][15][16] For example, Bach et al [17] adopted co-precipitation method to obtain CdS QDs at room temperature after vacuum distillation for 12 h.…”

Kumari et al [18] synthesized CdSe QDs by continuous stirring for 5 h at high pH level of 11. Cao et al [3] prepared CdSe QDs by using an improved organometallic synthesis method to dissolve sulfur powder and cadmium oxide in trioctylphosphine (TOP) at 240 • C. To date, most of the QD preparation techniques have been carried out under harsh conditions and often require lengthy reaction time and high synthesis temperature.…”
