Abstract: A solar wavelength-converter for converting higher energy shorter wavelength solar radiation to lower energy longer wavelength light, comprises: a transparent matrix having particles of at least one inorganic phosphor embedded in it in which the at least one phosphor is configured to absorb light of wavelengths between about 300 nm and about 480 nm and convert it to light with a wavelength greater than about 500 nm. The at least one phosphor can comprise: a YAG:Ce phosphor; a silicate-based phosphor of a form M2Sia4:Eu2+; a silicate-based phosphor of a form M3SiO5:Eu2+, where M is a divalent cation in the silicate-based phosphors or combinations thereof. The at least one phosphor can comprise particles of a size that is substantially transparent to solar radiation having a wavelength greater than about 460 nm.
