  • In this paper, a new type of near-infrared light source of PbSe quantum dots(QDs) is introduced. Its photoluminescence(PL) spectrum is narrow which effectively match the infrared absorption peak of targets gases. The 5.1 nm PbSe quantum dots are synthesized by using the coordination solvent method and deposited on the GaN chip(with a deposition thickness of 165.5 μm), then a photoluminescent near-infrared light source is fabricated after ultraviolet light treatment and curing. The first exciton absorption peak of the light source is located at 1 592 nm, the photoluminescence peak is located at 1 665 nm, and its emission spectrum contains the entire absorption spectrum of CH4 gas between 1 625-1 840 nm. The CH4 gas concentration detection experiment is carried out using this light source. The results show that the lowest detection limit of 100×10-6 and the detection error of 2% can be obtained. The new detection system composed of PbSe quantum dots near-infrared light source has the advantages of low power consumption, low cost and high efficiency. When it is used in gas detection, the filter can be omitted, and it has a broad application prospect in the field of infrared gas detection.
