| 中文摘要: |
| 采用溶胶-凝胶法制备了Tb3+掺杂40SrO-20B2O3-40SiO2发光玻璃,并进行了差热-热重分析以及发光性能检测。结果表明:玻璃制备温度需在1 200 ℃以上,样品剩余质量约为原料总质量的42%;玻璃在236 nm的紫外光激发下存在三个发射峰,分别位于489 nm,544 nm和586 nm处,其中544 nm峰值最强,且随着Tb3+掺杂浓度的增加,发射光谱强度先增大后减小,当掺杂浓度为5%时达到最大,Tb3+之间的能量传递方式为偶极-偶极相互作用;该玻璃的CIE色坐标为(0.257 2,0.566 7),发光颜色为黄绿色,色温为7 004 K,为冷色系。 |
| 英文摘要: |
| Tb3+ doping 40SrO-20B2O3-40SiO2 luminescent glass is prepared by the sol-gel method. Differential thermal and thermogravimetric analysis, and luminescence properties testing are conducted on this glass. The results show that the glass preparation temperature needs to be above 1 200 ℃, and the remaining weight of the sample is about 42% of the total raw material. Under excitation by 236 nm ultraviolet light, the glass exhibits three emission peaks located at 489 nm, 544 nm, and 586 nm respectively, with the peak at 544 nm being the strongest. As the Tb3+ doping concentration increases, the emission spectrum intensity first increases and then decreases, reaching a maximum at a doping concentration of 5%. The energy delivery mode between Tb3+ is dipole-dipole interaction. The CIE chromaticity coordinates of this glass is (0.257 2, 0.566 7), the luminescence color is yellowish-green, and the color temperature is 7 004 K, belonging to the cool color series. |
