摘要：Short-wave infrared imaging is playing an increasingly important role in present scientific research. However, the high experimental cost limits its application. Based on the upconversion fluorescence effect, we prepared a low-cost composite film for short-wave infrared imaging using upconversion particles and polydimethylsiloxane. The imaging quality and stability of the prepared composite films are examined using an infrared laser. The fluorescence density fluctuation of the composite films at 100 is only 1.2%, and the maximum value of the fluorescence power percentage error caused by the inhomogeneity is only 4.5%. Due to the affordable and easy accessibility, a typical optical laboratory can prepare and use the aforementioned technique in experiments in a short time.
