1. A solar spectral wavelength converting material comprising an aluminum hydroxide to which 1-pyrenecarboxylic acid is anchored by a process comprising combining an aluminum hydroxide precursor and 1-pyrenecarboxylic acid in a solvent having a boiling point of at least 200° C. and heating the mixture, followed by removing air and moisture and purging with inert gas, then heating the resulting mixture at a temperature and for a time sufficient to perform thermal decomposition.
