Abstract

An illumination system comprising a radiation source and luminescent material comprising a phosphor of general formula (Ba1-xSrx)1-aMg3-bA114O25:EuaMnb, wherein 0 < x < 1, 0 < a < 0.2, 0 < b < 0.2, a + b > 0 can provide composite white output light that has a greater amount of emission in the blue color range than the conventional lamp. This characteristic makes the device ideal for applications in which a true color rendition is required. The invention is also concerned with a blue to green phosphor of general formula (Ba1-xSrx)1-aMg3-bAl14O25:EuaMnb, wherein 0 < x < l, 0 ≤ a < 0.2, 0 < b < 0.2, a + b > 0.
