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 organic hybridized selenothulium stannate with photoelectric response performance and preparation thereof. The chemical name of the organic hybridized selenothulium stannate ispenta[N-(2-ethoxy) ethanediamine anion](hexaseleno distannic acid) trithulium hydrate. The invention adopts a structural formula as follows. The preparation comprises the following steps: separatelyadding 0.0097 g of Sn, 0.0065g of Se, 0.0130 g of KI, 0.0137g of TmCl3 and 2ml of N-(2-ethoxy) ethanediamine into a hard glass tube and sealing the two ends of the glass tube; and keeping the temperature of 160 DG C for 7-10 days, taking the glass tube out of an incubator, washing the mixture with absolute ethyl alcohol after being cooled, and drying the mixture at a constant temperature to obtainthe product, yellow particle crystals. The organic hybridized selenothulium stannate has the advantages that the process is simple, the organic hybridized selenothulium stannate is not easily dissolved in a common solvent, is high in yield and good in repeatability and the like.

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...
