Abstract
We introduce a strategy to develop multiple-phase structure of inorganic lead halide perovskite CsPbBr3. The method is based on local optical heating, which allows the creation of strong temperature gradients. Using Raman spectroscopy, it was determined that such gradients induce a distribution of phase transitions within the perovskite crystal. We show that such gradients lead to perovskite multiple-phase structure.
期刊介绍：
Optics and Spectroscopy (Optika i spektroskopiya), founded in 1956, presents original and review papers in various fields of modern optics and spectroscopy in the entire wavelength range from radio waves to X-rays. Topics covered include problems of theoretical and experimental spectroscopy of atoms, molecules, and condensed state, lasers and the interaction of laser radiation with matter, physical and geometrical optics, holography, and physical principles of optical instrument making.
