1. A quantum dot comprising
a semiconductor nanocrystal core comprising indium and phosphorus,
the quantum dot having an emission peak wavelength from about 600 nm to about 650 nm, or an emission peak wavelength from about 500 nm to about 550 nm,
wherein the quantum dot exhibits an area of a peak from about 400° C. to about 500° C. that is about 0.17 times to about 0.5 times relative to an area of a peak from about 200° C. to about 300° C. in a thermogravimetric analysis graph as determined with a differential scanning calorimeter.
