Problems solved by technology

[0003] At present, the research on photoelectric responsive materials is mainly concentrated on metal oxide semiconductors, which generally have a large band gap (the band gap is greater than 3.0eV), and only in the ultraviolet range (less than 5% of the total energy of sunlight) There is a photoelectric response in the visible light range (about 43% of the total energy of sunlight), which greatly limits their application under visible light irradiation.

Embodiment 1

[0025] 1. Preparation of penta[N-(2-hydroxyethyl)ethylenediamine anion](hexasanoic acid)trithulium with photoelectric response properties:

[0026] With Sn, TmCl 3 , Se and KI as raw materials, using the traditional hydrothermal synthesis method to cultivate crystals, 0.0097g Sn, 0.0065g Se, 0.0130g KI, 0.0137g TmCl 3 and 2ml of N-(2-hydroxyethyl)ethylenediamine were added to the hard glass tube, and the two ends of the glass tube were sealed. Keep it at 160 degrees Celsius for 7-10 days, take it out of the incubator, wash it with absolute ethanol after cooling, and then dry it at room temperature to obtain yellow granular crystals, which are penta[N-(2-hydroxyethyl ) Ethylenediamine anion] combined (hexasanoic acid) trithulium.

[0027] The prepared penta[N-(2-hydroxyethyl)ethylenediamine anion](hexasanoic acid)trithulium crystal was monochromated by graphite monochromator on the Brukesmart APEXIII CCD diffractometer. (λ=0.071073nm) rays, scan the diffraction data in ω-θ m...

Abstract

The invention discloses an organic hybrid thulium selenide stannate with photoelectric response performance and its preparation. Chemical name: penta[N‑(2‑hydroxyethyl)ethylenediamine anion](hexasanodistannate)thulium. Structural formula: 0.0097g Sn, 0.0065g Se, 0.0130g KI, 0.0137g TmCl 3 and 2ml N-(2-hydroxyethyl)ethylenediamine were added to the hard glass tube, and the two ends of the glass tube were sealed. Keep it under the condition of 160 degrees centigrade for 7-10 days, take it out of the incubator, wash it with absolute ethanol after cooling, and then dry it at normal temperature to obtain yellow granular crystals, which is the product. The advantages of the present invention: the present invention has the advantages of simple process, not easily soluble in common solvents, high yield and good repeatability.

Description

technical field [0001] The invention belongs to the field of rare earth cluster fluorescent materials. Specifically, it is an organic hybrid thulium selenide stannate with photoelectric response performance and its preparation. Background technique [0002] The increasingly serious energy crisis and environmental pollution are the most fundamental problems faced by human beings in the world. In order to solve these problems, it is hoped to find a photoelectric response material that can directly receive sunlight and undergo charge separation or charge transfer process to form photovoltage or Photocurrent, and achieve the conversion of solar energy into usable or storable energy. In fact, as early as 1912, Ciamici was the first to discover photoelectric responsive materials, and proposed to use solar energy to drive organic synthesis. Subsequently, Fujishima and Honda discovered a photoelectric response material with better comprehensive performance, which is anatase. The a...
