Abstract
Terbium acetylacetonate hydrate (TAH)-doped poly methyl methacrylate (PMMA) with varying proportions was synthesized using the solvent evaporation method. Absolute spectral parameters of the samples under the excitation of a 308-nm light-emitting diode were derived adopting the integrating sphere method. The total radiant fluxes of typical visible emissions in 1, 2, and 3 wt% TAH doping PMMA samples are calculated to be 67.84, 80.16, and 93.90 μW, respectively, and the total luminous fluxes are determined to be 36.95, 43.16, and 50.18 millilumens. The results indicated that PMMA including TAH generates new applications as an efficient ultraviolet→visible conversion layer in enhancing the photovoltaic efficiency of solar cells.
