Direct deposition of inorganic–organic hybrid semiconductors and their template-assisted microstructures

A straight-forward method is developed to deposit a new class of self-organized inorganic–organic (IO) hybrid, (C12H25NH3)2PbI4. These IO hybrid structures are stacked-up as natural multiple quantum well structures and exhibit strong room-temperature exciton emission and other multifunctional features. Here it is successfully demonstrated that these materials can be directly carved into 2D photonic structures from the inexpensive template-assisted electrochemical deposition followed by solution processing. The applicability of this method for many such varieties of IO-hybrids is also explored. By appropriately controlling the deposition conditions and the self-assembly templates, target structures are developed for new-generation low-cost photonic devices.
