An intrinsic fiber-optic sensor to detect volatile organic compounds (VOCs) at room temperature is described. The sensor consists of a multimode fiber coated with a zinc oxide (ZnO) nanoparticle layer. The ZnO layer is deposited on the fiber surface after etching a portion of the fiber cladding to increase the evanescent interaction between the light and ZnO layer. Adsorption of VOCs on the ZnO layer changes its refractive index, resulting in a light intensity change. The interaction process of the light carried by the fiber with the VOCs is observed in absorption spectra. The sensor responds to methanol and acetone vapor concentration ranging from 5%-50%..
