Material Properties
Perovskite Structure: MAPbBr₃ crystallizes in a cubic or orthorhombic perovskite structure, depending on temperature.
Semiconducting Behavior: Exhibits a bandgap of ~2.2 eV, making it suitable for optoelectronic applications requiring visible light absorption and emission.
High Photoluminescence Quantum Yield (PLQY): Efficient luminescence, making it an ideal material for perovskite-based light-emitting devices.
Excellent Stability: More stable than MAPbI₃ in ambient conditions due to the presence of bromine.
Applications
Perovskite Light-Emitting Diodes (PeLEDs):
Strong photoluminescence and high quantum yield make MAPbBr₃ a key material for perovskite-based LEDs and displays.
Photodetectors:
Strong absorption in the visible region enables high-performance visible-light photodetectors.
X-ray Detection & Scintillators:
Used in X-ray detectors and scintillator materials for imaging applications.
Solar Cells (Wide Bandgap Layer):
Utilized in tandem perovskite solar cells as a wide-bandgap absorber.
Nonlinear Optics & Transparent Electronics:
Explored for use in nonlinear optical materials and transparent conducting materials.
