Embodiment 1

[1824] Embodiment 1: Preparation of inorganic nanoparticles

[1825]The nanoparticles used in the examples herein were prepared according to the method published by Lhuillier E. and Ithurria S. et al., (Lhuillier E. et al., Acc.Chem.Res., 2015, 48(1) , pp 22–30; Pedetti S. et al., J.Am.Chem.Soc., 2014, 136(46), pp 16430–16438; Ithurria S. et al., J.Am.Chem.Soc., 2008 , 130, 16504–16505; Nasilowski M. et al., Chem. Rev. 2016, 116, 10934-10982).

[1826] The nanoparticles used in the examples herein were selected from the group consisting of CdSe / CdZnS, CdSe, CdS, CdTe, CdSe / CdS, CdSe / ZnS, CdSe / CdZnS, CdS / ZnS, CdS / CdZnS, CdTe / ZnS, CdTe / CdZnS, CdSeS / ZnS, CdSeS / CdS, CdSeS / CdZnS, CuInS 2 / ZnS, CuInSe 2 / ZnS, InP / CdS, InP / ZnS, InZnP / ZnS, InP / ZnSeS, InP / ZnSe, InP / CdZnS, CdSe / CdZnS / ZnS, CdSe / ZnS / CdZnS, CdSe / CdS / ZnS, CdSe / CdS / CdZnS , CdSe / ZnSe / ZnS, CdSeS / CdS / ZnS, CdSeS / CdS / CdZnS, CdSeS / CdZnS / ZnS, CdSeS / ZnSe / ZnS, CdSeS / ZnSe / CdZnS, CdSeS / ZnS / CdZnS, CdSe / ZnS / CdS, CdSeS / ZnS / CdS, CdS...

Embodiment 2

[1827] Example 2: Ligand Exchange for Phase Transfer to Basic Aqueous Solutions

[1828] CdSe / CdZnS nanosheets and 3-mercaptopropionic acid suspended in 100 μL of heptane were mixed and heated at 60° C. for several hours. The nanoparticles were precipitated by centrifugation and dispersed in dimethylformamide. Next, after adding potassium tert-butoxide to the solution, ethanol was added and centrifuged to precipitate. Finally, disperse the colloidal nanoparticles in water.

Embodiment 3

[1829] Example 3: Ligand Exchange for Phase Transfer to Acidic Aqueous Solutions

[1830] CdSe / CdZnS nanosheets suspended in 100 μL of alkaline aqueous solution were mixed with ethanol and centrifuged to pellet. The PEG-based polymer was dissolved in water and added to the precipitated nanosheets. Acetic acid was dissolved in the colloidal suspension to control the acidic pH.

Abstract

The present invention relates to a composite particle (1) comprising a plurality of nanoparticles (3) encapsulated in an inorganic material (2), wherein the plurality of nanoparticles (3) is uniformlydispersed in said inorganic material (2). The present invention also relates to a light emitting material, a support supporting at least one composite particle (1) and/or a light emitting material and an optoelectronic device comprising at least one composite particle (1) and/or a light emitting material.

Description

technical field [0001] The invention relates to a composite material particle comprising a plurality of nano particles uniformly dispersed and encapsulated in an inorganic material. In particular, the present invention relates to a composite material particle with fluorescent properties. Background technique [0002] In order to be able to represent various colors, it is generally possible to carry out by mixing at least three complementary colors, especially the three colors red, green and blue. In the chromaticity coordinate diagram, the color that can be expressed by mixing three monochromatic colors in different proportions is the three chromaticity coordinates of the three monochromatic colors (such as red, green, and blue), and the triangle formed contains subset of . The range of this subset constitutes the so-called color gamut. Most color display devices operate on the three-color principle: each pixel includes three sub-pixels, one red, one green and one blue, w...
