Abstract As typical nano metarials in near infrared waveband, PbSe Quantum Dots have a very large exciton Bohr radius of 46 nm and a small band gap of 0.28 eV at room temperature. PbSe QDs have very unique properties, such as the quantum confined optical property, and which possess high photoluminescence (PL) quantum yield (QY) with size dependent tunable wavelength emissions. By analyzing the luminescence spectrum of PbSe Quantum Dots, a method through adjusting the particle size of PbSe Quantum Dots (QDs) to match gas absorption spectrum was presented in this paper. 4.6 and 6.1 nm PbSe QDs were synthesized and deposited on the GaN chip to fabricate the NIR QDs light sources. The PbSe QDs-UV glue composites thickness was determined to be 48.0 and 671.5 μm for 6.1 and 4.6 nm PbSe QDs. The NIR QDs were used to detect the C2H2 and NH3 gas. The experiments show that the PL spectrum of 4.6 nm NIR QDs can cover the entire absorption spectrum of C2H2 gas (from 1 500 to 1 550 nm) and the PL spectrum of 6.1 nm NIR QDs can cover the entire absorption spectrum of NH3 gas (from 1 900 to 2 060 nm). By changing the quantum size of QDs, the PL peak of the NIR QDS light source can be adjusted to cover the absorption peak of different gases. The matching method presented in this paper is efficient and feasible, which has great application potential in gas detection.
