Abstract: This contribution consists in a microreview of our research activities for the last three years period concerning the synthesis and characterisation of M@ZnO nanocolloids with M = Ti, Eu, Co and [Mo₆Br₁₄]²⁻. Using, these different |polymeric| nanocolloids, thanks to the high concentration, we demonstrate the possibility to prepare various functional nanomaterials like gels, nanosized powders or functional thin films (oxynitrides or oxides) with numerous shapes such as plates and fibres. Versatile |ZnTiON| coloured or Eu,Ti@ZnO red-luminescent thin films are developed.

Keywords: zinc oxide; oxynitride; europium; transition metal clusters; luminescence; DLS; photocatalysis; nanocolloids; thin films; nanotechnology; nanomaterials; gels; nanopowders.
