Abstract: This invention relates to luminescent materials for ultraviolet light or visible light excitation containing lead and/or copper doped chemical compounds. The luminescent material is composed of one or more than one compounds of aluminate type, silicate type, antimonate type, germanate/or germanate- silicate type, and/or phosphate type. Accordingly, the present invention is a good possibility to substitute earth alkaline ions by lead and copper for a shifting of the emission bands to longer or shorter wave length, respectively. Luminescent compounds containing copper and/or lead with improved luminescent properties and also with improved stability against water, humidity as well as other polar solvents are provided. The present invention is to provide lead and/or copper doped luminescent compounds, which has high color temperature range about 2,00OK to 8,000K or 10,000K and CRI over 90.

Abstract translation: 本发明涉及含有铅和/或铜掺杂化合物的紫外光或可见光激发用发光材料。 发光材料由铝酸盐型，硅酸盐型，锑酸盐型，锗酸盐型或锗酸 - 硅酸盐型和/或磷酸盐型的一种或多种化合物组成。 因此，本发明很有可能用铅和铜代替碱土离子，将发射带分别移动到更长或更短的波长。 提供含有铜和/或铅的发光化合物，其具有改善的发光性能，并且还具有改善的对水，湿度以及其它极性溶剂的稳定性。 本发明提供铅和/或铜掺杂的发光化合物，其色温范围大约为200K至8000K或10,000K，CRI高于90。
