More Information
Summary:Disclosed herein are wavelength converting compositions, wavelength converters and light sources including the same. The wavelength converting compositions include at least one poly(silphenylene-siloxane) gel matrix that contains at least one wavelength conversion material, such as one or more phosphors in powdered and/or particulate form. Methods of making such compositions and converters are also disclosed. Wavelength converted light sources such as wavelength converted light emitting diode packages are also disclosed. The poly(silphenylene-siloxane) gel matrix exhibits relatively high thermal stability, as well as desirable optical properties.
