摘要

合成了一种由稀土离子与N-苯基邻氨基苯甲酸(N-HPA)和邻菲咯啉(phen)形成的蓝色发光配合物。该配合物是典型的配体发光配合物

其发射峰位于444nm

激发波长为334nm和407nm。元素分析、红外光谱、紫外可见光谱和差热-热重的分析结果表明:配合物中含有大量的N-HPA和相对较少的稀土离子和phen

其中稀土离子与N-PA中的羧酸根配位

而N-PA中的氨基通过氢键与phen的氮原子结合

形成了有利于配体之间的能量传递和电子转移的通道。稀土离子Tb

的共同存在促进了这一能量转移通道的形成

进而强化了配体的蓝色发射。

Abstract

A great number of rare earth (Tb

) complexes with aromatic carboxylic acid

β-diketone and phen etc. organic ligands have been synthesized

and their excellent luminescence properties have been used as luminescence materials and probe in the chemical and biological molecular systems. Very recently

a 10 candela-class white LED composed of a multiple quantum well InGaN blue light-emitting diode (LED) and a YAG:Ce phosphor has been developed.The white light is obtained by the integration of the blue InGaN LED die and the YAG phosphor into a single package. Several approaches are available to manufacture white LEDs

the thinking at several companies is that a violet or near-UV LED plus RGB phosphors will be the best overall method to make a white LED. In order to prepare high efficiency phosphor-based LED for general lighting

it is necessary to find some suitabl e phosphors for this purpose. In the present paper

a novel blue emission com plex of rare earth ions Tb

with N-phenylanthranilic acid and 1

10-phenanthro line was synthesized and characterized by luminescence spectra

IR spectra

UV-v is absorption spectra

DTA-TG and element analysis. It was found that the complex is a typical ligand emitting complex

which possess a strong emission spectra with peak wavelength lying at 444nm

and a wide excitation spectra with two adjace nt peaks at wavelengths 337nm and 407nm.This means that the synthesized blue phosphor can be used for the assembler of a new kind of blue LED. Results from the IR

U V-vis absorption spectra

DTA-TG and element analysis show that the comple x contained a great of N-PA and a little of rare earth as well as phen

the rare earthions coordinated with carboxyl group

and the azyl of N-PA link with phen through the nitrogen atom by the formation of hydrogen bond

which composes a good channel for the energy and electrons transmitting between ligands. The co-existence of rare earth ions(Tb

) will enhance the formation of this channel and then intensify the ligands’ blue emission.
