Large (up to 20 nm) quantum dots (QD) of indium antimonide were synthesized using colloidal chemistry at elevated temperatures (250-300 °C). In terms of optical and electrophysical characteristics, they exhibit properties similar to those of conventional QD (4-5 nm), with the difference that the spectral maximum of luminescence is shifted inappropriately to the size difference. This, together with measurements of the QD shape by transmission electron microscopy, may indicate a deterioration in the perfection of the crystal structure of large QD, possibly due to insufficient synthesis temperature
