Preparation method of yttrium phosphate nano material

Abstract

The invention belongs to the technical field of synthesis of functional materials and relates to a preparation method of an yttrium phosphate nano material. The method comprises the following steps: firstly, dissolving yttrium oxide in nitric acid and reacting to generate yttrium nitrate liquor; then, dissolving diammonium hydrogen phosphate particles in secondary distilled water to obtain diammonium hydrogen phosphate liquor; then, diluting the yttrium nitrate liquor and heating to almost boiling, and slowly dropwise adding the diammonium hydrogen phosphate liquor and continuously stirring to obtain a white turbid liquid; centrifuging the obtained white turbid liquid, pouring a supernatant liquid out, and washing the centrifuged precipitate with water and then centrifuging again; repeating the above processes till the pH of the centrifuged supernatant liquid is equal to 7, and washing to obtain purified precipitate; and then, drying the purified precipitate in a vacuum drying box, placing in a platinum crucible, and roasting in a chamber electric furnace to obtain the yttrium phosphate nano material. The preparation of the yttrium phosphate nano material is simple in preparation process, mild in reaction condition, low in energy consumption, low in cost, easy to operate and environment-friendly, and the prepared yttrium phosphate nano material is high in purity.

Description

Technical field: [0001] The invention belongs to the technical field of functional material synthesis, and relates to a synthesis and purification process of a luminescent host material yttrium phosphate nano material, in particular to a preparation method of yttrium phosphate nano material. Background technique: [0002] Yttrium phosphate has excellent thermophysical and chemical properties. It can be used as a matrix component, activator, sensitizer and coating of luminescent materials, and can also be used as a matrix for laser crystals. It has a wide range of potential applications in dense sintering. Lanthanide rare earth elements Ions have unsatisfactory 4f electron orbitals. The electron energy levels on the 4f orbitals are abundant, which are 1-3 orders of magnitude more than the number of electronic energy level transitions of other elements. They have many excellent photoelectric properties, and their spectrum can emit from the ultraviolet region. For light of various w...
