The central atom in NH3, which is ammonia, undergoes sp3 hybridization. This means that the nitrogen atom in NH3 forms four hybrid orbitals by mixing one 2s orbital and three 2p orbitals. These hybrid orbitals are arranged in a tetrahedral geometry around the nitrogen atom. In NH3, the three...
The central atom in NH3 is nitrogen. In NH3, the central nitrogen atom undergoes hybridization to form its bonding orbitals. The type of hybridization that occurs in NH3 is sp3 hybridization. In sp3 hybridization, one s orbital and three p orbitals of the central atom combine to form four sp...
The band gap of MAPbI3 is 1.56 eV while it is 1.69 eV for MA0.5PbI3. The increased band gap is caused by the enhanced hybridization between I−-5p and Pb2+- 6p atomic orbitals and the conduct band minimum shifting about 0.1 eV to the high energy level, as explained in ...

Metal halide perovskite nanocrystals are promising materials for a diverse range of applications, such as light-emitting devices and photodetectors. We demonstrate the bandgap tunability of strongly emitting CH3NH3PbBr3 nanocrystals synthesized at both room and elevated (60 °C) temperature through the...
