Preparation, optical properties, and thermal stability of polyvinyl butyral composite films containing core (lanthanum hexaboride)–shell (titanium dioxide)-structured nanoparticles

Nano-sized lanthanum hexaboride (LaB6)@ titanium dioxide (TiO2) particles with a core–shell structure has been successfully synthesized via a simple sol–gel method. LaB6@TiO2 particles were used as filler in polyvinyl butyral (PVB) matrix and performance of the TiO2 shell was evaluated. The core–she...
