Embodiment 1
[0017] Example 1: 65SiO 2 -25Na 2 O-5BaO-5ZnO-3mol%Nd 2 o 3 , doped with 0.3.wt%β-SiAlON:Eu 2+ phosphor, and 1 wt.%CaAlSiN 3 :Eu 2+ Phosphor powder;
[0018] Weigh SiO with a purity greater than 99.9% according to the stoichiometric ratio 2 、Na 2 O, BaO, ZnO, Nd 2 o 3 Place in an alumina crucible, melt at 1450°C for 30 minutes, then water quench and dry to obtain glass without phosphor powder. After pulverizing the glass and commercially available β-SiAlON:Eu with a purity greater than 99.99% 2+ Phosphor and CaAlSiN 3 :Eu 2+ Phosphor powder is evenly mixed according to the mass ratio. The mixture was pressed, then sintered in air at 600° C. for 1 h, and then cooled naturally to obtain the glass.
Embodiment 2
[0019] Example 2: 65SiO 2 -25Na 2 O-5BaO-5ZnO-4mol%Nd 2 o 3 , doped with 0.3.wt%β-SiAlON:Eu 2+ phosphor, and 2 wt.%CaAlSiN 3 :Eu 2+ Phosphor powder;
[0020] Weigh SiO with a purity greater than 99.9% according to the stoichiometric ratio 2 、Na 2 O, BaO, ZnO, Nd 2 o 3 Put it in an alumina crucible, melt it at 1300°C for 60 minutes, then water quench and dry to obtain glass without phosphor doped. After pulverizing the glass and commercially available β-SiAlON:Eu with a purity greater than 99.99% 2+ Phosphor and CaAlSiN 3 :Eu 2+ Phosphor powder is evenly mixed according to the mass ratio. The mixture was pressed, then sintered in air at 500° C. for 2 h, and then cooled naturally to obtain the glass.
Embodiment 3
[0021] Example 3: 65SiO 2 -25Na 2 O-5BaO-5ZnO-5mol%Nd 2 o 3 , doped with 0.3.wt%β-SiAlON:Eu 2+ phosphor, and 3wt.%CaAlSiN 3 :Eu 2+ Phosphor powder;
[0022] Weigh SiO with a purity greater than 99.9% according to the stoichiometric ratio 2 、Na 2 O, BaO, ZnO, Nd 2 o 3 Place it in an alumina crucible, melt it at 1400°C for 40 minutes, then water quench and dry to obtain glass without phosphor powder. After pulverizing the glass and commercially available β-SiAlON:Eu with a purity greater than 99.99% 2+ Phosphor and CaAlSiN 3 :Eu 2+Phosphor powder is evenly mixed according to the mass ratio. The mixture was pressed, then sintered in air at 550° C. for 1.5 h, and then cooled naturally to obtain the glass.
