A study was conducted on the size-dependent decoherence for the semiconductor microcrystallites. It was found that microcrystallites with larger sizes have shorter coherence time of the exciton states. If the system was initially in the superposition of two different excitonic coherent states, the coherence characteristic time depends on both the sizes of the microcrystallites and the overlap between the two coherent states.
