Two halo-phosphate/borate phosphors blue-emitting CaCl apatite Eu2+ (CCAP Eu2+) and yellow-emitting Ca2BO3Cl Eu2+ were synthesized and used as down-conversion luminescent materials to fabricate a series of white light-emitting diodes (WLEDs) with near-UV LEDs and their optical properties were investigated Adjustable correlated color temperature can be realized by simply controlling the blending ratio of the blue and yellow phosphors The fabricated white LEDs exhibited promising properties including a high current durability a wide range of tunable correlated color temperature (4000-8000 K) acceptable color rendering index (78-86) Crown Copynght (C) 2010 Published by Elsevier B V All rights reserved
