ResumoA chemical synthesis is described in which ZnSe:Cu particles slowly grow to a final size of ∼3.5 nm radius in 4 h reaction time. During particle growth, samples are extracted to study the luminescence as a function of particle size and temperature. Quantum size effects are observed to influence both the ZnSe and the Cu2+ luminescence. Temperature-dependent measurements on the luminescence intensity, lifetime, and peak positions are reported and discussed.
