Regulation strategy of white emission from organic–inorganic hybrid metal halide perovskites

Abstract

White light emitting materials (WLEMs), especially single component WLEMs, have always been a research hotspot for their great application potential in the white-light emitting diodes (WLEDs). However, the white-light performance...

Synthesis and structure-dependent optical properties of two new organic–inorganic hybrid antimony(iii) chlorides

“…5,6 To tune the coordination geometries of metal ions and the connection modes of metal halide polyhedra, different organic molecules (e.g., amines, quaternary phosphonium salts, amino acids, and ionic liquids) have been adopted as structure-directing agents (SDAs). [7][8][9][10][11][12][13] Luo and co-workers reported the synthesis of the layered halide perovskite (R/S-PPA)EAPbBr 4 (PPA = 1-phenylpropylamine and EA = ethylammonium) with an excellent photoconductivity and robust polar photovoltage effect by alloying a small EA cation into the chained halide perovskite (R/S-PPA)PbBr 3 . 14 Kanatzidis and co-workers illustrated that the octahedral distortion and white-light emission in twodimensional (2D) lead bromides were strongly affected by the sizes and shapes of different amines intercalated within the halide perovskite layers.…”

Lead-free hybrid indium perovskites with near-unity PLQY and white light emission using an Sb3+doping strategy

“…The use of larger organic cations to construct single-crystal bulk materials with 0D structures is an effective way to obtain suitable hostguest systems. [27][28][29][30] This is because larger organic cations make it easier for luminescent substances to be regularly embedded in the host matrix without causing the formation of electronic bands. As the dimensions vary from 3D, 2D to 1D and 0D, the strong electron-phonon coupling increases, leading to the formation of commonly recognized self-trapping excitons (STEs).…”

Panchromatic luminescent D–π–A benzothiazoles with different π-bridging modulation: design, synthesis and application in WLED devices

“…1 Light-emitting diodes (LEDs) and organic LEDs (OLEDs) have attracted wide attention by virtue of their advantages of low energy consumption and high efficiency. [2][3][4] Thus, white LEDs (WLEDs) are gradually replacing traditional lighting devices, such as incandescent and fluorescent lamps. [5][6][7] In general, white light emission is obtained by combining the three primary colors (red, green, and blue) or two complementary colors (red-cyan, greenmagenta, and blue-yellow/orange).…”
