Abstract

Experiments were carried out with different semitransparent and colorless luminophores, so that passive energy facades of urban buildings capture effective energy through their glass. Inorganic dyes are used with rare earth elements such as Eu3 + and Nd3 + / Yb3 + lanthanide pair, to move solar spectrum towards nir wavelength range, which is the near infrared (nir) spectral region from the end of the highest visible lengths (around 780 nm) up to 3000 nm (13000 cm-1 to 3300 cm-1 ), combined with nanostructured silica particles to increase the luminescent quantum yields and brightness. User acceptance study based on emotions, considers the acceptance degree regarding presence of color in glass. Experimental results demonstrate optical power efficiency, higher with inorganic dyes (2.2%) than lanthanides (1.3%) for samples of crystals with Luminescent Solar Concentrators (csls) of 3.5 x 3.5 cm2 tinted and fully transparent, with optical transmittance ≈ 90%. Question about the presence of color in glass and its relationship with energy efficiency is solved.
