- Abstract
- This work focuses on the development of EU2+-doped strontium (Sr)-borate as a yellow-emitting phosphor and its application to the fabrication of white light-emitting diodes (LEDs). Synthesis of Eu2+-doped Sr-borate phosphors was finely tuned for obtaining the efficient yellow luminescence through varying host composition, Eu concentration, and firing temperature. The 1300 degrees C-fired Eu2+-doped Sr3B2O6, which was found to be the most efficient candidate to date, was used for white LED fabrication. Their optical properties were evaluated, resulting in warm white lights with CIE chromaticity coordinates of (0.340-0.372, 0.287-0.314) and color rendering indices of 75-77 under the forward currents of 5-40 mA.
