The film samples were previously plated onto glass substrates.
The specific steps and processes are as follows:
(1) a7101 glass slide (25.4 mm. times.76.2 mm. times. (1-1.2) mm) was cut to a size matching the liquid sample well of the instrument (for example, UV-visible spectrophotometer UV-2600, Youngi instruments Inc.) itself, i.e., 12 mm. times.36 mm. times. (1-1.2) mm. Ultrasonically cleaning and drying the mixture by acetone, alcohol and deionized water for later use.
(2) A transparent PET double-sided tape with a width of 12 mm was stuck to the center of a clean slide glass with a size of 12 mm × 36 mm × 1-1.2 mm.
(3) A small-size (less than or equal to 10mm multiplied by 10 mm) film sample is stuck to the central part of the transparent PET double-sided adhesive tape. The small-sized film sample is provided with a glass or other transparent material substrate, and the substrate needs to be clean before being pasted.
(4) And (3) pasting the rest areas except the thin film on the glass slide by using a shading adhesive tape (such as a black single-sided adhesive tape and the like) to ensure that the areas except the thin film of the glass slide are light-tight, thereby finishing the thin film sample.
The utility model has the advantages that:
the utility model discloses do not change, do not increase ultraviolet-visible spectrophotometer's any device, utilize the sample groove of instrument from the area, adopt common material and corresponding operating method just can test the transmission spectrum of the small-size film sample that is less than or equal to 10mm x 10mm, simple, nimble, easy going, solved the difficult problem that small-size film material can't direct measurement at ultraviolet-visible spectrophotometer.
