<p>PROBLEM TO BE SOLVED: To provide a liquid observation environment cell device, which allows for high resolution observation when used in a transmission electron microscope, and expresses localized plasmon resonance, at a low manufacturing cost.SOLUTION: A liquid observation environment cell C consists of a lower sealing layer 1 of 10 nm thick composed of carbon, an adhesive layer 2 of 10 nm thick composed of ceramics, a metal layer 3 of 10 nm thick for adsorbing a molecule M, and an adhesive layer 4 of 10 nm thick composed of ceramics. In order to express plasmon resonance, the metal layer 3 is composed of Au, Ag, Cu or Al, and the diameter D of the opening OP in the adhesive layer 2, metal layer 3 and adhesive layer 4 is from several tens nm to 500 nm ((A) of Fig. 3). The molecule M is adsorbed to the wall surface of the metal layer 3. On the adhesive layer 4, an upper sealing layer 5 of 10 nm thick composed of carbon is formed ((B) of Fig. 3). An electron beam EB proceeds from the upper sealing layer 5 toward the lower sealing layer 1, and a TEM image is obtained. Cross-sectional observation of solid (wall surface of the metal layer 3)/liquid interface, and cross-sectional observation of the molecule M are possible ((C) of Fig. 3).</p> |
