Abstract (en)
[origin: WO2012079863A1] The composition of the invention includes: an inorganic core and an aluminate shell, said aluminate being of the formula (CeaTbb)Mg1+xAl11+yO19+x+y (1), where a, b, x and y comply with the relations a+b=1-0.2 = x = +0.2 and -0.2 = y = +0.2, wherein the shell uniformly covers the inorganic core over a thickness of no less than 300 nm. The phosphor of the invention is obtained by calcinating the composition of the invention at a temperature of at least 1200°C.
