Enhanced photoluminescence of morin–bovine serum albumin on porous anodized aluminum oxide

In this paper, the photoluminescence (PL) of porous anodized aluminum oxide (AAO) impregnated with essentially nonfluorescent morin and morin–bovine serum albumin (BSA) was investigated for the first time, respectively. The evident PL bands similar to that of morin–Al 3+ complex in solution were obs...

Description
Summary:In this paper, the photoluminescence (PL) of porous anodized aluminum oxide (AAO) impregnated with essentially nonfluorescent morin and morin–bovine serum albumin (BSA) was investigated for the first time, respectively. The evident PL bands similar to that of morin–Al 3+ complex in solution were observed and the intensity of the latter with morin–BSA was much greater than that of the former with only morin. Moreover, the enhancement increased with the larger pore diameter of the AAO membranes. The appearance of PL bands might be ascribed to the formation of morin–Al complexes in the AAO pores with its inner wall involved. A likely orderly luminescent model was proposed to be responsible for the observed enhancing phenomena of PL due to the coexistence of morin and BSA in the AAO pores.
