Is this comparison can give more information regarding the preferred orientation of low-dimensional perovskite film? Layered 2D Perovskite thin film shows repetitive PXRD peak partner.
Because of the paculiar architecture of 2DLP and their preferencial orientation parallel to the substrate, provide intense basal reflection from the 00l plane, of the inorganic layer. However, if you break the orientation by grinding the powder you may also get the other reflections, masked otherwise. However,
In the case of thinfilm your material is constrained to the substrate and you end up with the intense basal reflections.
