Determination of Optical Properties in Germanium Carbon Coatings Deposited by Plasma Enhanced Chemical Vapor Deposition

In this research, Germanium-carbon coatings were deposited on ZnS substrates by plasma enhanced chemical vapor deposition (PECVD) using GeH4 and CH4 precursors. Optical parameters of the Ge1-xCx coating such as refractive index, Absorption coefficient, extinction coefficient and band gap were measured by the Swanepoel method based on the transmittance spectrum. The results showed that the refra...

Chemical Vapor Deposition of Antimicrobial Polymer Coatings

There is large and growing interest in making a wide variety of materials and surfaces antimicrobial. Initiated chemical vapor deposition (iCVD), a solventless lowtemperature process, is used to form thin films of polymers on fragile substrates. To improve research efficiency, a new combinatorial iCVD system was fabricated and used to efficiently determine the deposition kinetics for two new po...

Growth of coatings on nanoparticles by photoinduced chemical vapor deposition

Photoinduced chemical vapor deposition was used to grow organic coatings on NaCl nanoparticles. Aerosolized nanoparticles were mixed with a vapor-phase coating reactant and introduced into a room-temperature, atmospheric-pressure cell, where the mixture was exposed to 172-nm radiation from a Xe2* excimer lamp. Several coating reactants were investigated; the most successful was methyl methacryl...
