Solar radiation shielding properties of transparent LaB6 filters through experimental and first-principles calculation methods

Abstract Solar radiation shielding properties of transparent LaB 6 filters were investigated experimentally and by a first-principles method. It was found that the calculated solar radiation shielding performances for transparent LaB 6 filters are in excellent agreement with experimental findings. The results indicate that LaB 6 is a promising near infrared (NIR) shielding material for solar radiative filters with high visible light transmittance and perfect optical performance that can be applied not only to compacted filters but also in the nanoparticle dispersed coatings.
