WebApr 12, 2024 · In our experiments, CsPbBr 3 perovskite is used as the gain/loss material (behaving as a lossy material in the absence of external pumping) because of its high optical-gain coefficient, low cost, and easy fabrication (38, 39). The pumped microcavity, nonpumped MW, and TW are made of CsPbBr 3 perovskite to facilitate sample preparation. WebLight Scattering Techniques. For laser diffraction and X-ray diffraction, small angle X-ray diffraction (SAXS), wide angle X-ray diffraction (WAXS), we harness the principle that particles of different sizes have a unique light scattering signature, so by accurately measuring the light scattering over a wide range of angles with high sensitivity and at …
