Abstract:
Colloidal chemistry techniques at elevated temperatures (250–300$^\circ$C) have been used to synthesize big (up to 20 nm) quantum dots (QDs) based on indium antimonide (InSb). In respect to their optical and electrical characteristics, the obtained big QDs exhibit properties similar to those of QDs with usual dimensions (4–5 nm), except the spectral maximum of luminescence being shifted inadequately to the size difference. This circumstance, together with the QD shape as measured by transmission electron microscopy, can be indicative of a less perfect crystalline structure of obtained big QDs, probably resulting from insufficiently high temperature of synthesis.
Keywords:
colloidal quantum dots, indium antimonide, synthesis, luminescence, current–voltage characteristics.
