Figure 6From: Solvothermal synthesis, growth mechanism, and photoluminescence property of sub-micrometer PbS anisotropic structuresPhotoluminescence spectrum of PbS microstructures obtained with different processes. (a) Without surfactant at 165°C for 12 h (T165), (b) without surfactant at 180°C for 12 h (T180), and (c) with 3.6 × 10−3 M SDBS at 180°C for 12 h (T180SDBS).Back to article page
