摘要: 非接触式实时温度监测在诸多领域具有重要的意义，然而现有的温度器在分辨率和响应速度方面存在局限性。在本研究中，我们利用自还原手段合成得到了混合价态Eu2+/Eu3+共掺杂Sr0.8Ca0.2BPO5荧光粉，利用该荧光粉双发射峰的特点实现了自参比荧光测温。在303 K到570 K的范围内，该温度传感器的相对灵敏度和绝对灵敏度分别高达4.63% K−1与0.00189 K−1，且具有高分辨率和快速响应特征，验证了该荧光粉在非接触式温度传感领域的潜在应用价值。
Abstract: Non-contact real-time temperature monitoring is of great significance in numerous fields; however, existing thermometers have limitations in terms of resolution and response speed. In this study, mixed-valence Eu2+/Eu3+ co-doped Sr0.8Ca0.2BPO5 phosphors were synthesized via a self-reduction method. Leveraging the characteristic of dual emission peaks of these phosphors, self-referenced fluorescence thermometry was achieved. Within the temperature range of 303 K to 570 K, the relative sensitivity and absolute sensitivity of this temperature sensor reached as high as 4.63% K−1 and 0.00189 K−1, respectively, while exhibiting high resolution and rapid response features. These results validate the potential application value of this phosphor in the field of non-contact temperature sensing.
