摘要:
为了探究稀土离子掺杂铝硅酸盐的光温特性，本文采用燃烧合成法制备了系列荧光粉材料Ca1-3x/2Al2Si2O8：xEu3+。X射线衍射结果表明掺杂Eu3+离子不会改变基质CaAl2Si2O8的晶体结构。荧光光谱结果表明该荧光粉在近紫外光区域具有较强吸收，当被波长为393 nm的近紫外光激发后，其最大特征发射峰为611 nm，且Eu3+离子的最佳掺杂浓度为0.05。利用上升时间测温法研究了CaAl2Si2O8：Eu3+荧光粉的光温传感特性，结果表明：随着Eu3+掺杂浓度的增加，上升时间单调递减，但当掺杂掺杂超过0.100时就会发生淬灭。Ca0.985Al2Si2O8：0.01Eu3+的相对灵敏度随温度的升高先增大后减小，并在520 K时达到最大值（0.024 K-1）。上述研究表明该荧光粉具备优异的温度传感性能，在测温领域具有广泛的应用前景。
Abstract:
To investigate the optical temperature characteristics of rare earth ion doped aluminosilicate，a series of phosphor materials Ca1-3x/2Al2Si2O8：xEu3+ were prepared by combustion synthesis. The X-ray diffraction results show that the doping of Eu3+ ions does not change the crystal structure of the matrix CaAl2Si2O8. Fluorescence spectroscopy results show that the phosphor has strong absorption in the near-ultraviolet region. When excited by near-ultraviolet light with a wavelength of 393 nm，the phosphor material exhibits the maximum characteristic emission peak at 611 nm，and the optimal doping concentration of Eu3+ ion is 0.05. The optical temperature sensing characteristics of CaAl2Si2O8：Eu3+ phosphors were studied by the rise time method. The results show that the rise time monotonously decreases with the increase of Eu3+ doping concentration，but quenching occurs when the doping concentration exceeds 0.100. The test results of Ca0.985Al2Si2O8：0.01Eu3+ show that the relative sensitivity increases first and then decreases with the increase of temperature，and reaches the maximum value of 0.024 K-1 at 520 K. The above research indicates that the phosphor has excellent temperature sensing performance and has broad application prospects in the field of temperature measurement.
