SrSiAlN_3:Eu~(2+)/胶黏剂复合材料荧光的压应力传感特性

摘要
首次研究了红色宽带发光的SrSiAlN_3:Eu~(2+)荧光粉与胶黏剂组成复合材料后的力敏荧光特性,分析了样品形状和胶黏剂成分对复合材料压敏荧光特性的影响。荧光压应力传感实验系统由力加载装置与荧光发射光谱测试系统组成。实验结果表明SrSiAlN_3:Eu~(2+)荧光粉/胶黏剂复合材料的荧光特征参数"谱带重心"随压应力增大而蓝移,而荧光强度和谱峰频移均不表现出明显的压敏性。样品几何形状的差异不影响压应力传感灵敏度。谱带重心波长的力致移动具有可重复性,相应得到荧光粉/硅胶、荧光粉/H610应变胶两款复合材料的谱带重心波长移动应力传感的灵敏度分别为0.20 nm/MPa及0.31 nm/MPa,均较常规的红宝石荧光压谱系数高三个数量级以上,系统的分辨力达0.055 MPa。实验结果表明SrSiAlN_3:Eu~(2+)/胶黏剂复合材料是性能良好的光学无线应力传感敏感材料。
Stress-dependent fluorescence of SrSiAlN_3:Eu~(2+)/resin composites and their stress sensing applications were studied for the first time. The experimental setup is a combination of a force loading apparatus and a fiber optic spectrometer. When a novel spectral characteristic-band barycenter-was employed for the active materials' emission spectra,blue-shift of the emission band barycenter was found with an increasing load of compressive stress onto the fluorescent composite. However,the intensity and peak wavelength of the fluorescence failed to be stress sensing signals. Repetitive calibration tests on the phosphor/silicone and phosphor/H610 composites gave piezospectroscopic coefficients as 0.20 nm/MPa and 0.31 nm/MPa,respectively. Such values are more than a thousand times of the coefficient of ruby,the standard piezospectroscopic material. Geometry of samples have no observable influence on the sensitivity. The sensing setup has a resolution fine as 0.055 MPa. The observation implies that the phosphor can be a candidate active material for optical wireless stress mapping.
