Hot-carrier cooling and photoinduced refractive index changes in organic–inorganic lead halide perovskites

Metal-halide perovskites are at the frontier of optoelectronic research due to solution processability and excellent semiconductor properties. Here we use transient absorption spectroscopy to study hot-carrier distributions in CH3NH3PbI3 and quantify key semiconductor parameters. Above bandgap, non-resonant excitation creates quasi-thermalized carrier distributions within 100 fs. During carrier...

Organic/inorganic hybrid as anticratering agent in cathodicelectrocoating

An improved aqueous electrocoating composition containing an anticrater additive which is a reaction product of silane component based on glycidoxy propyl tri methoxysilane and poly oxy propylene diamine. Materials were studied by infrared spectroscopy and particle size analyzer. Crater number of electrocoated sample was evaluated by GM9532p standard. The final electrocoat contains anticrater a...

High Refractive Organic–Inorganic Hybrid Films Prepared by Low Water Sol-Gel and UV-Irradiation Processes

Organic-inorganic hybrid sols (Ti-O-Si precursor) were first synthesized by the sol-gel method at low addition of water, and were then employed to prepare a highly refractive hybrid optical film. This film was obtained by blending the Ti-O-Si precursor with 2-phenylphenoxyethyl acrylate (OPPEA) to perform photo-polymerization by ultraviolet (UV) irradiation. Results show that the film transpare...

Molecular design of hybrid organic-inorganic materials

Hybrid organic-inorganic materials offer a wide range of interesting applications especially in optics. Chemistry plays a major role in the elaboration and comprehension of such materials. Sol-gel process provide a method to blend, down to the molecular scale, organic and inorganic components. Examples of hybrid organic-inorganic materials for optics and optical characterizations of hybrid mate...
