Embodiment 1

[0050] Sodium gadolinium tetrafluoride (chemical formula NaGdF 4 ) is the preparation of up-conversion fluorescent nanomaterials as substrates.

[0051] According to the molar ratio of sodium fluoride: gadolinium fluoride: erbium oxide: ytterbium oxide 1:1:0.01:0.1, weigh 5 grams of the four compound powders, of which sodium fluoride is 0.7012g, gadolinium fluoride is 3.5771g, Erbium oxide is 0.0639g, and ytterbium oxide is 0.6578g. Put the mixed powder in the powder container and fully stir and grind, so that the powders of each compound are mixed evenly. The powder is delivered through the powder feeding conduit and the powder feeding nozzle, and then 2g of the mixed powder is weighed out. It is processed by pressing a steel mold with a diameter of 18mm. It is 6MPa, and the duration is 6s. After the end, a formed tablet with a certain density can be obtained, with a diameter of 18mm and a thickness of 1mm.

[0052] Place the obtained pellets in a high temperature resistan...
