Functional capacities of lead halide perovskites are strongly dependent on their morphology, crystallographic texture, and internal ultrastructure the nano- meso-scale. In last decade, significant efforts directed towards development novel synthesis routes that would overcome morphological constraints provided by physical properties these materials. contrast, various living organisms, such as unicellular algae, have ability to mold biogenic crystals into a vast variety intricate nano-architectured shapes while keeping single crystalline nature. Here, using cell wall dinoflagellate L. granifera model, sustainably harvested calcite is successfully transformed nano-structured perovskites. Three variants CH3 NH3 PbX3 generated with X = Cl- , Br- I- ; exhibiting emission peak-wavelength ranging from blue, green, near-infrared, respectively. The approach can be used for mass production desired morphological, textural and, consequently, exploiting numerous templates forming organisms.
