Abstract
Different ratios of aluminum were incorporated into MCM-41. PL measurements revealed a blue shift and an enhancement in intensity by 2 orders of magnitude as the Si : Al ratio was decreased to 14. By comparing the PL and the photoluminescence excitation (PLE) spectra of aluminosilicate MCM-41 to silica MCM-41 and to published reports on similar materials, we are able to identify the origin of the photoluminescence enhancement.
