Embodiment 1
[0031] According to the chemical formula Eu 1.9 Yb 0.1 MoB 2 o 9 The stoichiometric ratio of each element in the element is weighed respectively as europium oxide Eu 2 o 3 : 0.059 g, ytterbium oxide Yb 2 o 3 : 1.248 g, ammonium molybdate (NH 4 ) 6 Mo 7 o 24 4H 2 O: 0.601 g, boric acid H 3 BO 3 : 0.4204 grams, after grinding and mixing uniformly in an agate mortar, select the air atmosphere for the first calcining, the temperature is 350 ° C, and the calcining time is 8 hours, then cooled to room temperature, and the sample is taken out. After the first calcination of the raw materials, the mixture is fully mixed and ground again, and the second sintering is carried out at 700°C in an air atmosphere. The sintering time is 8 hours, cooled to room temperature, and the sample is taken out. After the raw material is calcined for the second time, the mixture is fully mixed and ground evenly, and then sintered for the third time at 850°C in an air atmosphere. The sinteri...

[0036] According to the chemical formula Pr 1.8 Yb 0.2 MoB 2 o 9 The stoichiometric ratio of each element in , respectively weighed praseodymium oxide Pr 6 o 11 : 1.0214 g, ytterbium oxide Yb 2 o 3 : 0.1314 g, ammonium molybdate (NH 4 ) 6 Mo 7 o 24 4H 2 O: 0.601 g, boric acid H 3 BO 3 : 0.4204 g, ground and mixed uniformly in an agate mortar, and then calcined for the first time in an air atmosphere at a temperature of 400 ° C for 7 hours, then cooled to room temperature, and the sample was taken out. After the first calcination of the raw materials, the mixture was fully mixed and ground again, and the second sintering was carried out at 630°C in an air atmosphere. The sintering time was 7 hours, cooled to room temperature, and the samples were taken out. After the raw materials are calcined for the second time, the mixture is fully mixed and ground evenly again, and then sintered for the third time at 900°C in an air atmosphere, the sintering time is 7 hours, an...
Embodiment 3
[0039] According to the chemical formula Nd 1.6 Yb 0.4 MoB 2 o 9 The stoichiometric ratio of each element in the formula is weighed to take neodymium oxide Nd 2 o 3 : 0.8973 g, ytterbium oxide Yb 2 o 3 : 0.2627 g, ammonium molybdate (NH 4 ) 6 Mo 7 o 24 4H 2 O: 0.601 g, boron oxide B 2 o 3 : 0.2367 grams, ground in an agate mortar and mixed evenly, select the air atmosphere for the first calcining, the temperature is 500 ° C, the calcining time is 8 hours, then cooled to room temperature, and the sample is taken out. After the first calcination of the raw materials, the mixture was fully mixed and ground again, and the second sintering was carried out at 680°C in an air atmosphere. The sintering time was 7 hours, cooled to room temperature, and the samples were taken out. After the raw materials are calcined for the second time, the mixture is thoroughly mixed and ground evenly, and then sintered for the third time in an air atmosphere at 800°C for 6 hours and cool...
