Abstract

The invention discloses an inorganic-organic hybrid material with high water stability and blue-green emission and photoelectric response performance, which is based on silver bromide, 1,2-bistriphenylphosphinebromoethane (1,2 ‑DBTPP·2Br) as the reaction raw material, prepared by a simple solution evaporation method, it has good water stability, and exhibits blue-green emission and good photoelectric response performance (photocurrent is 0.17 Ua), and can be used in liquid phase The light-emitting and photoelectric switching device in the system has the advantages of low preparation cost, simple operation method and high yield.

Description

technical field [0001] The invention belongs to the technical field of material preparation, and specifically relates to an inorganic-organic functional hybrid material with high water stability and blue-green emission and photoelectric response performance and a preparation method thereof. Background technique [0002] Luminescent materials are widely used in lighting, display, information display and visualization devices, trace detection, chemical sensors, biomarkers, etc. In this field, silver halide-based photoluminescent (PL) materials have attracted much attention due to their extraordinary structural diversity and photophysical properties. What's more, they are low-cost and non-toxic compared to the precious metals gold, iridium and rare earth metals. So far, from a structural point of view, silver bromide-based PL materials can be divided into two types: one composed of neutral organic ligands (e.g., cubane[Ag 4 Br 4 R 4 ]) coordinated neutral silver halides; th...
