A silicone product 100, a lighting unit comprising the silicone product and a method of manufacturing a silicone product are provided. The silicone product 100 comprises polymeric material 110, luminescent material 130 and filler particles 120. The polymeric material 110 comprises a material of the group of polysiloxanes. The polymeric material 110 being light transmitting. The luminescent material 130 comprises particles which have at least in one dimension a size in the nanometer range. The luminescent material 130 is configured to absorb light of a first spectral range and to convert a portion of the absorbed light into light of a second spectral range. The filler particles 120 are of a light transmitting inert material. The filler particles 120 are miscible with the luminescent material 130. The filler particles 120 are provided in the polymeric material 110. The particles of luminescent material 130 are distributed along a surface of the filler particles 120.
