Pb 2+ is a low cost activator which can provide strong absorption of UV and an efficient conversion to longer wavelengths. Considering that aluminate hosts are used in some lamp phosphors, Pb 2+ luminescence in these hosts is studied. This paper reports results on the luminescence of Pb 2+ in aluminates. It was found that the position of Pb 2+ emission can be manipulated by selecting the size of the host cations. The findings are important in context of the role of Pb 2+ as a sensitizer.
