Phase Transitions and Stabilization of the Organized Hybrid Langmuir-Blodgett Films of Alkanoic Acids/CdS and PbS Q-Particles

Identification of the phase transition (see Figure) that occurs at the early stages of the topotactic transformation of Langmuir–Blodgett films of Cd or Pb behenate and arachidate with H2S has led to clarification of the structures of the hybrid films, previously in question. The ordered phase is stabilized by the addition of thio-carboxylic acids to the system.
