Abstract

Semiconductor microcrystallites with a characteristic diameter of 15-200 Å can easily be made by precipitation in liquids (water, alcohols). The spectra show partially resolved discrete features resulting from carrier confinement in three dimensions.1 Semiconductor quantum dots of comparable size can also be prepared in suitable glass hosts, such as borosilicate glasses.2
