Preparation method of rare earth doped zirconia fluorescent marking material, product and application thereof

Abstract

The invention provides a preparation method of a rare earth doping zirconium dioxide fluorescence labeling material as well as a product and application thereof. Zirconium salt and erbium salt are added into deionized water to be dissolved according to the mol ratio; acetic acid and trans-butene diacid are added; the obtained solution is transferred into a glass bottle with a Teflon bottle cap; aglass bottle containing a solution is put into a preheated 120 DEG C hydrothermal kettle; the constant temperature maintenance is performed for 24 to 36 hours; after taking out, reaction products arecollected and are crystals at the bottle bottom. The crystals are sequentially washed once respectively by deionized water and ethanol; drying is performed at room temperature; Er-Zr-MOF powder is obtained. The method has the advantages that the process is simple; the cost is low; the operation is easy. The obtained powder has the smaller particle diameter; the particle distribution is uniform; the specific surface area is larger; more surface state is realized; more luminous centers can be accommodated; the illumination efficiency is higher. The luminous powder is excited by laser being 280 nm; the luminous peak is about 630 nm.

Description

technical field [0001] The invention relates to a preparation method of a nano fluorescent marking material, more precisely to a preparation method of a rare earth-doped zirconia fluorescent marking material and its product and application, belonging to the field of luminescent materials in luminescence physics. Background technique [0002] Rare earths are a huge treasure trove of luminescent materials. Whether rare earth elements are used as the matrix part of luminescent (fluorescent) materials, or as activators, co-activators, sensitizers or dopants, the luminescent materials made Generally collectively referred to as rare earth luminescent materials or rare earth fluorescent materials. Because there are 4f orbitals in the electron configuration of the rare earth element atoms, when the 4f electrons jump from a high energy level to a low energy level by radiative galloping, they emit light of different wavelengths. Rare earth element atoms have abundant electronic energ...

Problems solved by technology

However, when the doping concentration is too high, due to the shortening of the distance between the rare earth ions and the strengthening of the interaction, the rare earth ions at a high energy level can easily transfer their energy to the host material through surface defects, thereby reducing the fluorescence emission intensity, which is the concentration Quenching phenomenon
