The invention discloses a thin film field effect transistor type gas sensor and a preparation method thereof. The sensor is a thin film field effect transistor with a bottom gate top contact type structure or a bottom gate bottom contact type structure. A thin film field effect transistor with a bottom grid top contact structure is taken as an example. The transistor comprises a substrate, a gateinsulating layer and a channel active layer from bottom to top. The channel active layer is a quantum dot thin film. A source electrode and a drain electrode are deposited above the substrate. A gateelectrode is further led out of the substrate. The internal composition, the structure, the overall process of the corresponding preparation method and the parameters during all steps of the preparation method of the thin film field effect transistor type gas sensor are improved. The quantum dot thin film serves as a channel active layer and a gas sensitive layer at the same time, and the gas response of multiple parameters is comprehensively regulated by utilizing the grid bias voltage. As a result, the prepared gas sensor is high in sensitivity, low in power consumption and high in selectivity. The effect of detecting low-concentration target gases, such as NO2 and H2S, is achieved.
