Method for preparing rhodamine intercalation hydrotalcite luminescent material

Abstract

A hydrotalcite composite luminescent material with rhodamine intercalation, which pertains to abio-organic composite luminescent material. The process is preparing solution A with mole ratio of bivalence and tervalence cation M2+ / M3+=2.0-4.0; adding laser dye sulphonated rhodamine and sodium salt of dodecylbenzene sulfonic acid into mixed solution of ethanol and water and fully dissolving to obtain solution of sulphonated rhodamine and dodecyl benzene sulfone acid group containing anion with negative charge B; mixing solution A, B into solution C, preparing NaOH solution; communicating solution C and NaOH solution into full-back-liquid mixing membrane reactor to react, mixing to obtain red slurry, introducing the red slurry into hydrothermal kettle, reacting, absterging by CO2, de-ionized water and absolute ethyl alcohol and centrifugally separating, vacuum drying. Then hydrotalcite system with co-intercalation of suphonated rhodamine and dodecyl sulfone acid group is obtained. Advantages of the invention are that dye molecular is immobilized, and fluorescence quenching caused by dye aggregation is reduced.

Description

technical field

[0001] The invention belongs to the field of inorganic-organic composite luminescent materials, and in particular provides a preparation method of a rhodamine-intercalated hydrotalcite composite luminescent material. Background technique

[0002] As a tunable laser with good performance, dye laser has the advantages of wide output spectral line range, high power and low price, and has good application value in military, medical and other fields. According to the state of the working substance, dye lasers can be divided into liquid dye lasers, solid dye lasers and gas dye lasers. At present, the most common one is liquid dye laser. However, this type of dye laser has the disadvantages of being flammable, explosive, difficult to remove, difficult to operate, and easy to cause environmental pollution. Compared with it, solid dye laser can overcome the above-mentioned liquid dye laser. Disadvantages, greatly reducing the harm of dissolved dyes to human health an...
