Beschreibung
Zusammenfassung:	The invention provides a high-color-rendering-index transparent ceramic for warm white light illumination and a preparation method thereof. The transparent ceramic with high structural rigidity is prepared through a coprecipitation method, when Ce is doped to replace Sr and Lu, low color temperature is displayed under excitation of light with a wavelength of 410 nm, so spectrum broadening is achieved, a color rendering index is increased, and the ceramic is quite suitable for indoor warm white light illumination. 本发明提供了一种暖白光照明用高显指透明陶瓷及其制备方法，采用共沉淀法制备了具有强结构刚性的透明陶瓷，掺杂Ce3+取代Sr2+和Lu3+时，在410 nm的激发下显示出较低的色温，实现了光谱展宽，提高了显指，非常适合用于适用于室内暖白光照明。
