Abstract

The invention discloses a method for synthesizing a one-dimensional red long afterglow material, and belongs to the technical field of preparation of a phosphor material. The method is characterized by comprising the steps of carrying out hydrothermal reaction on Y3<+>, Eu<3+>, Mg<2+>, and Ti<4+> at the same time to generate a Y(OH)3 precursor doped with Eu<3+>, Mg<2+>, and Ti<4+>, vulcanizing the precursor by mixture of carbon powder and sublimed sulfur to generate a one-dimensional Y2O2S:Eu<3+>, Mg<2+>, and Ti<4+> red long afterglow luminescent material. The red long afterglow luminescent material prepared by the method disclosed by the invention is low in crystallization temperature of the substrate; ions which need to be doped are doped into the substrate at the hydrothermal stage of fabricating the precursor; the good nano tubular structure of a sample can be kept in later vulcanizing and sintering processes; and the physical and chemical properties are stable.

Description

technical field [0001] The invention discloses a method for synthesizing a one-dimensional red long-lasting luminescent material, which belongs to the technical field of phosphorescent material preparation, and specifically relates to a method for combining Y 3+ 、Eu 3+ , Mg 2+ and Ti 4+ At the same time, the hydrothermal reaction produces Eu 3+ , Mg 2+ and Ti 4+ Doped Y(OH) 3 precursor, followed by sulfuration of Y(OH) with a mixture of carbon powder and sublimated sulfur 3 Prebody generation 1D Y 2 o 2 S: Eu 3+ , Mg 2+ , Ti 4+ Red long-lasting glow material approach. Background technique [0002] Rare-earth long-lasting luminescent materials can store energy under sunlight, and then slowly release energy in a dark background to emit light. This feature is widely used in low-light lighting, emergency instructions, architectural decoration and other fields. In recent years, Later, it gradually expanded to high-tech fields such as optical information storage...
