Abstract: A method of making a wavelength converter includes (a) combining a luminescent material and inorganic nanoparticles with a liquid methoxy methyl polysiloxane precursor to form a liquid dispersion, the precursor having a methoxy content of 10 to 50 weight percent (wt %), the inorganic nanoparticles including at least 10 weight percent of the dispersion; (b) applying the liquid dispersion to a non-stick surface; (c) curing the liquid dispersion to form a filled polymer sheet; and (d) cutting the sheet to form individual wavelength converters having a desired shape.
