Embodiment 1
[0028] Ba 6.88 B 3 SiO 13 Cl:0.12Dy 3+ Synthesis of luminescent materials.
[0029] Weigh 3.41 grams of barium carbonate, 4.63 grams of boric acid, 0.15 grams of silicon dioxide, 0.133 grams of ammonium chloride and 0.0372 grams of dysprosium trioxide according to the stoichiometric ratio, put the weighed raw materials in an agate mortar, grind the powder Grind finely and mix well.
[0030] Then the mixed raw materials were placed in a corundum boat, heated to 1000°C at a rate of 100°C / hour in an air atmosphere in a high-temperature box furnace, and kept at this temperature for 12 hours, and then slowly cooled to room temperature.
[0031] The sintered sample was ground into powder, washed three times with deionized water and ethanol to remove residual impurities, and dried at 200°C for 2 hours to obtain a luminescent powder with uniform particle size.
[0032] For prepared Ba 6.88 B 3 SiO 13 Cl:0.12Dy 3+ As for the luminescent material, the inventor has done structu...

Embodiment 3
[0040] Ba 6.70 B 3 SiO 13 Cl:0.30Eu 2+ Synthesis of luminescent materials.
[0041] Weigh 3.33 grams of barium carbonate, 4.63 grams of boric acid, 0.15 grams of silicon dioxide, 0.133 grams of ammonium chloride and 0.264 grams of europium trioxide according to the stoichiometric ratio, put the weighed raw materials in an agate mortar, grind the powder Grind finely and mix well.
[0042] Then the mixed raw materials were placed in a corundum boat, and heated to 1000°C at a heating rate of 100°C / hour in a high-temperature tube furnace under the protection of a mixture of hydrogen (5%) and nitrogen (95%), and This temperature was maintained for 12 hours, followed by slow cooling to room temperature.
[0043] The sintered sample was ground into powder, washed three times with deionized water and ethanol to remove residual impurities, and dried at 200°C for 2 hours to obtain a luminescent powder with uniform particle size.
[0044] With reference to the assay method of embod...
