Abstract
  • The in situ synthesis and patterning of pis nanocrystals (NCs): is obtained: by laser processing. of a transparent polymer matrix doped with a. Cadmium thiolate Methylimidazole (MI): modified complex, [Cd(SBz)(2)](2)center dot MI. The precursor molecule structure ensures a uniform distribution inside the polymer and gives,rise to a regular and homogeneous net-Work of CdS NCs in the quantum size regime with finely tunable bandgap by varying the laser fluence in the range 25-75 mJ cm(-2) and Shot number from 10. to 100. The simultaneous in situ synthesis of CdS NCs and patterning,has been performed in confined regions with a 10 mu m resolution by scanning the focused laser beam in the polymer/precursor composite: The emission signal of the irradiated regions presents contributions from both the band gap. and the defect emission band; around 3.4 and 2.2 eV, respectively, the relative intensity of them depending on the laser fluence and number of shots. Complex geometries of mu-patterned CdS NCs inside the polymer matrix are achievable, thus enlarging the perspectives in the development of nanodevices and organic light emitting diode(OLED) systems.
