本研究作為溫度感測微粒技術之改良與延伸，改善單色溫度感應循跡微粒之量測誤差，以應用於非侵入式地測量流體流動時之溫度分布。利用攪拌製程將兩種不同溫度敏感性之量子點CdZnSeS/ZnS、CsPbBr3塗覆於聚醯胺微粒的表面上，藉由兩種不同的溫度感測材料之螢光相對強度比進行自我校正正規化，可消除光照度不均勻、光源不穩定、微粒聚集、光漂白和微粒大小等因素所造成的誤差。溫度之計算則使用光強度量測法將量測之螢光強度轉換為溫度。經過實驗比較發現，在製備之製程中兩種量子點同時塗覆實驗結果CsPbBr3放射光峰值為12890.98，CdZnSeS/ZnS放射光峰值為63687.88，差距4.94倍，改為先後塗覆的方法並優化兩種量子點之比例後，CsPbBr3放射光峰值為59105.29，CdZnSeS/ZnS放射光峰值為59483.94，兩種量子點之峰值強度比例結果縮小至峰值幾乎相同。雷射功率之對兩種量子點強度比值之實驗結果則大致為逆相關之規律。最後，溫度可視化之實驗驗證結果發現製備之溫度感應循跡微粒之螢光強度與溫度關係在(溫度範圍內)可由二次曲線擬合，驗證溫度感應微粒之適用性。

This study is an improvement and extension of temperature sensitive particle technique, and the goal is improve the measurement error of single color temperature sensitive tracer particles for non-invasively measurement of the temperature distribution of the fluid flow. Two different temperature sensitive quantum dots (Quantum Dot, QD) CdZnSeS/ZnS、CsPbBr3 are coated on the surface of polyamid seeding particles by a stirring process. By utilizing the ratio of two different temperature sensitive materials, an self-calibrated normalized calibration curve can be obtained to eliminate errors caused by nonuniform illumination, nonuniform coating density, photobleaching and particle size variations. The temperature is calculated by converting the measured fluorescence intensity to temperature using an intensity-based method. The simultaneous coating test results show the peak of CsPbBr3 emission is 12890.98 and the peak of CdZnSeS/ZnS emission is 63687.88, corresponding to a 4.94 times intensity difference. After changing the coating method to sequential coating and optimizing the ratio of the two quantum dots, an comparable intensity peaks of CsPbBr3 emission (59105.29) and CdZnSeS/ZnS (59843.94) can be achieved. The experimental results of laser power to the relative intensity of the two quantum dots follow an inverse correlation. Lastly, the temperature visualization results show that the relationship between the fluorescence intensity of the prepared temperature sensitive tracer particles and the temperature (in the temperature range) can be fitted by the quadratic curve to verify the applicability of the temperature sensitive particles.
