Problems solved by technology

However, there are currently two problems in the research of new organic-inorganic hybrid fluorescent materials: (1) the fluorescent color is not easy to adjust; (2) it is unstable when heated; (2) it is not easy to obtain a pure phase
These issues limit the practical application range of new organic-inorganic hybrid fluorescent materials

example 1

[0014] Example 1: 0.1105g (0.50mmol) of analytically pure zinc acetate with 2 crystal water, 0.1967g (2.0mmol) of 2-methylpiperazine and 1.0ml (4mmol) of 50% by weight 2-hydroxyl The aqueous solution of phosphonic acid and acetic acid was dissolved in 8ml of distilled water under magnetic stirring. The obtained mixture was transferred to 25ml pressure melting bomb, and the lid was tightly closed. Placed in the autoclave, sealed, transferred to the oven at 160°C and kept warm for 120°C. hour. After the reaction, the reaction kettle was cooled to room temperature with an oven at a cooling rate of 3°C / hour. The pH of the solution after the reaction is between 3.6-4.1. The product was soaked in distilled water, cleaned with ultrasonic, and the turbid liquid was poured out. Repeated this many times, and finally dried naturally in the air to obtain a clean and colorless [(C 5 H 14 N 2 )Zn 10 (HO 3 PCH(OH)CO 2 ) 2 (O 3 PCH(OH)CO 2 ) 6 ·4H 2 O]·4H 2 O bulk crystals, the yield was 41%.

Abstract

The invention relates to a material with adjustable fluorescent color and the synthesis method thereof. The material is colorless crystal with the chemical formula of ((C5H14N2)Zn10(HO3PCH(OH)CO2)2(O3PCH(OH)CO2)6*4H2O)*4H2O and is synthesized by the hydrothermal method. The material has purple fluorescent light, and the color of the fluorescent light can turn to yellow and jacinth when the material is respectively subjected to annealing at 200 and 300 DEG C; specifically, the material can emit green yellow, blue purple and near white fluorescent light when subjected to annealing at 250 DEG C and excited by UV rays with wavelengths of 254, 340 and 365 nm. The material has the advantages of simple preparation technology, low requirement for equipment and low cost, and can be widely applied to the fields of high and new technology such as anti-counterfeit, optical fiber communication, photonic switch and optical waveguide owing to the crystal state of the sample.

Description

Technical field [0001] The invention relates to a fluorescent color adjustable material and a synthesis method thereof. Background technique [0002] With people’s in-depth research on the mechanism of fluorescence, fluorescent materials are used in lighting, light conversion films, decoration, anti-counterfeiting, biological probes, high-density and ultra-thin optical storage, electroluminescence, photoconductive, optical information transmission, x-ray imaging, The application range of dyes, molecular electronics, laser and scintillation counting technology is becoming wider and wider. Traditional fluorescent materials mainly include organic fluorescent materials (such as aromatic fused ring compounds with rigid structures and intramolecular charge transfer compounds with conjugated structures) and inorganic fluorescent materials (II A Group of magnesium, calcium, barium or II B Sulfides, oxides, tungstates, silicates, etc. of the group of zinc and cadmium as the matrix, and ra...
