Description

光源的发光物质及其相关的光源
本申请是国际申请日为2000年7月8日(国际申请号为PCT/DE00/02241)、进入国家阶段申请号为00801494.9的题为“光源的发光物质及其相关的光源”的申请的分案申请。
技术领域
本发明涉及一种用于通过发射蓝光的辐射源激发的具有石榴石结构A3B5O12的发光物质及其相关的光源。特别涉及用于以具有可见蓝光光谱范围的短波长的光源激发而产生白光的发黄光的石榴石-发光物质。特别适合作为灯(特别是荧光灯)或LED(发光二极管)的光源。
背景技术
由WO 98/05078中已知一种用于光源的发光物质以及其光源。其中作为发光物质,采用结构为A3B5O12的石榴石,其作为第一组分A的基质晶格由稀土金属Y、Lu、Sc、La、Gd或Sm中的至少一种组成。第二组分B采用元素Al、Ga或In中的一种。作为掺杂物质仅使用Ce。
由WO 97/50132中已知一种极类似的发光物质。其中作为掺杂物质可使用Ce或Tb。Ce发射黄光谱范围的光,而Tb发射绿光谱范围的光。在这两种情况下,互补色原理(发蓝光的光源和发黄光的发光物质)可用于产生白光。
最后,EP-A 124175中描述一种荧光灯,它除充有水银外还含有多种发光物质。这些发光物质通过UV-辐射(254nm)或通过460nm的短波长辐射激发。三种发光物质的选择要使其合成为白色(颜色混合)。
发明描述
本发明的目的是制备一种用于通过发射蓝光的辐射源激发的具有石榴石结构A3B5O12的发光物质,该发光物质耐高热负荷,并很适合用于可见光短波光谱范围内的激发。
该目的由一种用于通过发射蓝光的辐射源激发的具有石榴石结构A3B5O12的发光物质来解决,其中辐射源的发射在短波光学光谱范围420-490nm范围内,该发光物质以Ce活化,相应于式A3B5O12:Ce,其中第二组分B是元素Al和Ga中的至少一种,其特征在于,第一组分A含有Tb。第一组分A主要或仅由Tb组成。该发光物质可通过430-470nm范围的辐照而激发。作为第一组分除Tb外还有Y、Gd、La和/或Lu中的成分。
根据本发明,应用一种在光学短波范围内发射的用于光源的发光物质,它具有石榴石结构A3B5O12,并以Ce掺杂,其中该第二组分B是Al和Ga元素中的至少一种,该第一组分A含有铽(Tb)。令人惊奇的是已经发现,Tb在特别情况下,即在420-490nm范围的蓝光激发时,作为发黄光的发光物质的基质晶格(石榴石的第一组分)的组成是适宜的,其活化剂是铈。至今当激发是通过阴极辐射(电子)或短波长UV-光子进行时,在这方面除铈外只有Tb被考虑作为绿光发射的活化剂或共活化剂。
这时,Tb可单独的或与稀土金属Y、Gd、La和/或Lu中的至少一种相组合用作石榴石的第一组分A的主要组分。
作为第二组分使用元素Al、Ga和In中的至少一种。活化剂是铈。
在一特别优选的实施方案中,采用如下结构的石榴石:
(Tb1-x-ySExCey)3(Al、Ga)5O12
其中:SE=Y、Gd、La和/或Lu;
0≤x≤0.5-y;
0<y<0.1。
该发光物质在420-490nm范围内吸收并因此通过蓝光源,特别是用于灯或LED的辐射光源的辐射而激发。用蓝光LED可达好的结果,其发射的最大值在430-470nm范围内。Tb-石榴石:Ce-发光物质的发射最大值在约550nm处。
这种发光物质特别适用于白光LED中,这是基于蓝光LED与含Tb-石榴石-发光物质的组合,该发光物质通过吸收部分蓝光LED的发射而被激发;并且其发射与LED的剩余辐射相补充而成白光。
Ga(In)N-LED特别适用作蓝色LED,但也可用任何另外的方法产生发射在420-490nm范围内的蓝光LED。特别是建议的主要发射范围为430-470nm,因为其效率最高。
通过选择稀土金属的种类和数量,可精调吸收光谱带和发射光谱带的位置,类似于文献中已知的YAG:Ce类型的其它发光物质。与发光二极管相结合x特别适合的范围是0.25≤x≤0.5-y。
y的特别有利的范围为0.02<y<0.06。
本发明的发光物质也适用于与其发光物质相组合。
下列结构的石榴石作为发光物质是很合格的:
(TbxSE1-x-yCey)3(Al、Ga)5O12
其中:SE=Y、Gd、La和/或Lu;
0≤x≤0.02,特别是x=0.01;
0<y<0.1,y经常为0.01-0.05。
一般地,较少量的Tb在基质晶格中主要用于改进已知的用铈活化的发光物质的性能,而加入较大量的Tb主要是有针对性地用于改变已知的用铈活化的发光物质发射的波长。因此,高含量Tb特别适于色温在5000K以下的白光LED。

图1为实施例1的Tb-石榴石-发光物质的发射谱;
图2为实施例1的Tb-石榴石-发光物质的亮度谱;

实施例10:
在白光LED中与GaInN同时使用这类发光物质时,采用类似WO97/50132中描述的结构。例如将相同份额的实施例1和实施例4的发光物质分散于环氧树脂中,并用该树脂混合物包住其发射最大值约为450nm(蓝光)的LED。这种制备的白光LED的发射谱示于图7。蓝光LED-辐射与黄色发光物质-发射的混合在这种情况下产生x=0.359/y=0.350的色位,相应于色温为4500K的白光。
上述的发光物质通常为深黄色。它在黄色光谱范围内发射。在加入Ge或单独用Ga代替Al时,发射更多向绿光的方向偏移,由此还实现较高的色温。特别是,为了能与所需的色位相协调,可混合采用含Ga(或含Ga、Al)的Tb-石榴石或纯的含Al的Tb-石榴石。
