We have studied the effect of synthesis conditions on the luminescence spectra of ultrafine CuI powders. The results demonstrate that synthesis conditions (the reductant of Cu2+, the anion of the copper(II) salt, initial solution concentrations, and the presence of a stabilizer) influence the size and shape of the forming CuI particles and, accordingly, their luminescence spectrum. The highest luminescence intensity near λmax ≅720 nm (λex ≅ 370 nm) is offered by regularly shaped tetrahedral particles 1.1–1.2 μm in average size.
