Metal quinolates, Liq Alq Znq Mgq exhibit efficient luminescence in blue green region and find applications as emission layer in OLEDs. In most of these quinolates the excitation spectra are broad in the range 350 to 410 nm, just short of emission spectra of efficient GaN based blue LEDs. In this paper we report metal quinolates synthesized by slightly modified method in which the excitation gets extended beyond 450 nm so that there is better overlap between emission spectra of blue LED and the excitation spectra. Therefore these phosphors may be used for PC-LED applications.
喹啉金属盐Liq、Alq、Znq、Mgq在蓝绿色区域表现出高效发光，并被用作有机发光二极管（OLED）的发光层。在大多数这些喹啉金属盐中，激发光谱在350至410纳米范围内很宽，刚好略短于高效氮化镓基蓝光发光二极管的发射光谱。在本文中，我们报道了通过略微改进的方法合成的喹啉金属盐，其中激发范围扩展到450纳米以上，从而使蓝光发光二极管的发射光谱与激发光谱有更好的重叠。因此，这些磷光体可用于功率型发光二极管（PC-LED）应用。
