Inorganic halide perovskites have been regarded as potential candidates for nonlinear optical (NLO) materials due to their large bandgaps and second-harmonic generation (SHG) effects. If these crystals exhibit anisotropy, birefringent phase-matching ability will undergo enhancement. In this study, a one-dimensional (1D) perovskite, RbGeI3, was experimentally synthesized. Its [GeI3]∞1 double chains are parallelly arranged, resulting in structural anisotropy with birefringence of 0.122@1064 nm, the largest one reported NLO-active inorganic perovskites, determined from first-principles calculations. Furthermore, comprehensive characterization involving Raman spectroscopy, absorption spectrum, powder SHG measurement conducted assess its suitability NLO applications.

Multisite modulation for organic-inorganic hybrid metal halides (OIMHs) plays an important role in the optimization of their photophysical performance. Herein, we proposed organic cation modification strategy on phosphorus sites based 1,2-Bis(diphenylphosphino)ethane (DPPE) by a simple one-pot solvothermal method. Three zero-dimensional (0D) manganese-based OIMHs, two novel MdppeMnCl4·H2O and EdppeMnCl4, as well byproduct [Mn(dppeO2)3][MnCl4] were obtained (Mdppe = methyl-coordinated with DPPE; Edppe ethyl-coordinated dppeO2 is oxidation DPPE). All samples possess four-coordinated [MnCl4]2- polyhedron, while contains another six-coordinated [Mn(dppeO2)3]2+ complex. According to relevant optical measurements, EdppeMnCl4 both show bright green emissions photoluminescence quantum yields 55.66% 80.42%, respectively. By contrast, shows orange emission that confirmed be associated Mn2+ ions temperature-dependent PL spectra. Based good stability solution processability luminescent ink was developed potential application display information encryption fields.
