Mononuclear Y(III), La(III), Gd(III) complexes ((CH)N[Ln(L)]) with tetradentate Schiff base ligands derived from chiral stilbenediamine were synthesized. The luminescence of these complexes exhibited different in luminescence color between the chiral complexes and the racemic complexes. In this presentation, luminescence properties on the crystalline powder of mononuclear Y(III), La(III), Gd(III) complexes were investigated in detail. It was found out that the different luminescence spectra of crystalline were observed in between chiral and racemic complexes, but the similar luminescence spectra were observed in the ground ones.
