The invention provides a spraying mechanism for preparing a rare earth luminescent material and a preparation method of the rare earth luminescent material. The spraying mechanism comprises an installation frame, a rotary spraying device arranged in the center of the installation frame in a penetrating mode, a graded liquid conveying system arranged on the rotary spraying device in a sleeving modeand a nozzle fixedly connected to the lower portion of the rotary spraying device, wherein a wall flow prevention device is further arranged below the installation frame; and the wall flow preventiondevice is positioned below the rotary spraying device. The nozzle on the rotation gear rotates around the center of a center wheel at the same speed and rotates around the center of the rotation gear, so that the requirement of uniform spraying of various rare earth and oxalic acid feed liquids is met, and the crystallization effect is good. The spraying mechanism is provided with the graded liquid conveying system, so that feed liquid at a spraying position can obtain approximately the same water pressure, and uniform spraying of the feed liquid is guaranteed.
Description
technical field [0001] The invention relates to the field of preparation equipment for luminescent materials, in particular to a spray mechanism for preparing rare earth luminescent materials and a preparation method thereof. Background technique [0002] The process of rare earth luminescence is the process in which external energy is transferred to the luminescence center, the luminescence center is excited, and then radiates back to the ground state to generate fluorescence. At present, the commonly used matrix materials generally include fluoride, sulfide, oxide and so on. The phonon energy of fluoride is the lowest, but it is easy to decompose at high temperature, and its chemical temperature resistance is poor. The sulfur element of sulfide will volatilize due to current excitation in application, which will cause relatively great damage to nature. The characteristic of oxide is chemical And high physical stability, strong structure. Often used oxides are y 2 o 3、 ...
