摘要：

In this article, we synthesized and characterized a novel bluish green phosphor for white light-emitting diodes. Eu2+-activated Ca12Al10.6Si3.4O32Cl5.4. The phosphor shows broad and strong absorption in the region (320-450 nm), which is essential for improving the efficiency and quality of white light-emitting diodes. When excited at 380 nm. the phosphor shows two emission bands at around 425 and 500 nm. The main emission peak of Eu2+-activated Ca12Al10.6Si3.4O32Cl5.4 exhibits red shift in comparison with that of Eu2+-activated Ca12Al14O33, which is due to the introduction of Si and Cl ions. The results show Ca12Al10.6Si3.4O32Cl5.4 is a promising host candidate for the phosphors. (C) 2009 Elsevier B.V. All rights reserved.
