The recombination lifetimes for the radial and angular quantum number conserved 1S–1S and 1P–1P transitions from three-dimensionally confined electrons in CdSxSe1-x were measured by time-resolved photoluminescence (PL). The assignment of the observed transitions was supported by calculations of eigen energy levels and squared matrix element ratio for these transitions as well as well-resolved PL peaks arising from 1S–1S and 1P–1P transitions.
