    摘要: The present invention relates to the use of photonic band gap materials with phosphors incorporated. Photonic band gap materials play an important role for LEDs as light sources in applications where either a high radiance is desirable or LEDs are used in optical systems. The optical properties of current LEDs are such that the radiance is rather low and cannot be increased by standard means. It is an object of the invention to improve the radiance of light emitting devices by making use of photonic band gap materials with phosphors incorporated. According to the invention there is provided as structured material comprising a photonic structure that adjusts a range of photon frequencies, also referred to as photon density of states, in specific directions only, further comprising phosphor material having at least one emission mode for which the photon frequency is in the range adjusted by the photonic structure wherein the structured material has a symmetry lower than cubic such that the photonic structure adjusts the generation of photons emitted via said it least one emission mode of the phosphor material in less than three directions in this way increasing the radiance.

    摘要: In the luminescent screen of a flourescent lamp an organic europium compound is incorporated for converting mercury radiation between 350 nm and 450 nm into red light. The organic europium compound is diluted in an organic polymer. When the fluorescent lamp is dimmed its colour point shifts into the red similar to incandescent lamps and not into the blue.
