 White light emitting diodes, leds, are expected to replace traditional lighting sources within the next 5 to 10 years due to their high efficiency, reliability, and long lifetimes. Leds use a combination of blue or near ultraviolet, NuV, LEDs and Phosphors to produce a warm light with low color temperature and high energy efficiency. New Phosphors are needed to absorb the excitation energy from the LEDs and emit visible light efficiently. The selection of these Phosphors should be based on their ability to absorb the wavelengths of the LEDs and emit light at the appropriate wavelengths. Additionally, the balance of light between the LEDs and the Phosphors must be carefully considered to achieve the desired color rendering index and color temperature.
