Abstract

A ceramic composite laminate includes a wavelength-converting layer and a non-emissive layer, wherein the ceramic composite laminate has a wavelength conversion efficiency (WCE) of at least 0.650. The ceramic composite laminate can also include a wavelength-converting ceramic layer comprising an emissive material and a scattering material, wherein the laminated composite has a total transmittance of between about 40% to about 85%. The wavelength-converting layer may be formed from plasma YAG:Ce powder.
