| 简介 |
The present invention provides an Al-C-O based phosphor using neither heavy metal nor rare metal and composed of elements with high environmental compatibility and excellent economic efficiency, wherein the wavelength of the peak intensity of the emission spectrum can be changed without changing the basic composition. An aluminium oxide phosphor which comprises aluminium (Al), carbon (C), and oxygen (O) respectively in an amount of 30 mol% < Al< 60 mol%, 0 mol% < C < 10 mol%, 30 mol% < O< 70 mol% is provided. The above problem is solved in the production of an Al-C-O phosphor comprising aluminium (Al), carbon (C), and oxygen (O) by heating and firing a mixture comprising an aluminium-containing compound and a coordinatable oxygen-containing compound. |
