Colloidal CdS:Mn nanoparticles were synthesized in water solutions of the
 polymer polyvinyl-pyrrolidone (PVP), the surfactant cetyl-trimethyl-ammonium bromide
 (CTAB) and the mixture of PVP and CTAB. The sizes of nanoparticles were determined
 by electron microscopy and optical absorption methods. The growth media influence on
 photoluminescence of nanoparticles has been studied. It has been shown that the
 chemical composition and structure of the adsorptive layer on the surface of
 nanoparticles can be used as a technological tool to control their light emission. The
 possibility to use CdS:Mn NPs grown in PVP as light-emitting labels in biological media
 has been demonstrated.
