1. A method for preparing 8-hydroxyquinoline calcium as a luminescent material comprises the steps of preparing 8-hydroxyquinoline calcium by a precipitation conversion method by taking calcium hydroxide as a raw material and deionized water as a solvent;

  • the method is realized by the following steps;

    1) preparing materials;

    adding raw materials into a container according to the mol ratio of calcium hydroxide to 8-hydroxyquinoline =1;

    2, adding deionized water according to the total amount of the raw materials, namely deionized water =1kg to 50L, and dissolving or uniformly dispersing;

    2) reaction;

    heating and stirring for 4 hours at the temperature of 80-100 ℃

    , wherein the stirring speed is 30 r/min;

    3) cooling and filtering;

    cooling to room temperature, filtering, and washing with deionized water at 85 ℃

    for 3-5 times;

    4) and (3) drying;

    transferring the product to an oven, raising the temperature to 105 ℃

    , preserving the heat for 1h, cooling to room temperature, and discharging to obtain the 8-hydroxyquinoline calcium with the purity of 97.42-98.26% and the yield of 79.27-86.72%.
