Optimizing angular or spatial colour homogeneity has become an important task in many general lighting applications and first requires a valid description of illumination colour homogeneity. We analyse different frequently used methods to describe co

Precise spectral and colorimetric simulations in commercial ray tracing software require realistic light source models, which provide spectral information as a function of angle and spatial dimension. We describe and validate a general workflow to cr

To simulate and optimize optical designs regarding perceived color and homogeneity in commercial ray tracing software, realistic light source models are needed. Spectral rayfiles provide angular and spatial varying spectral information. We propose a

LaPO4:Ce,Tb as a nanoscale phosphor is prepared via a microwave-accelerated synthesis in ionic liquids. The underlying approach results in non-agglomerated nanocrystals, 9–12 nm in size, and exhibiting quantum yields of 70 % (Tb-related emission) a
