Abstract
Nanometric silica helical ribbons are used as platforms 1) to graft Perovskyte nano crystals and 2) grow in-situ Perovskyte crystals having helical shape using supersaturated recrystallization method. For both systems, they show strong induced circular dichroism (CD) and induced circularly polarized luminescence (CPL) signals, with very high dissymetric g-factors. The signs of these signals depend on the handedness of the helices. Right-handed and left-handed PNCs show respectively positive and negative CD and CPL signals. Simulations based on the boundary element method demonstrate that the circular dichroism comes from the chiral shape of H-PNCs. Figure 1
