Embodiment 1
[0055] A method for preparing a wide-temperate terahertz wave detector, comprising the following steps:
[0056] (1) Under the protection of nitrogen, mix ammonium hexachloroiridate, nickel nitrate hydrate, ammonium ferrous sulfate hydrate, ethanol and propionic acid; then reflux and stir for 5 minutes, then add ammonia water; after 10 minutes of reaction, cool naturally to room temperature, add Ethyl acetate coagulation and centrifugation; the centrifuged precipitate was washed with water and dispersed in ethanol to obtain a dispersion system; then manganese acetate, cobalt nitrate, and water were added, stirred for 10 minutes, added samarium samarium, stirred for 1 hour, and the support layer precursor was obtained;
[0057](2) Add polyvinyl alcohol, hydrogen peroxide, and iron tetraphenylporphyrin to the dispersion system, stir at 50°C for 1 hour, then add 4,4-diaminophenylmethane, octamethylcyclotetrasiloxane, and stir under reflux 10 minutes, then concentrated to obtain a...
Embodiment 2
[0066] A method for preparing a wide-temperate terahertz wave detector, comprising the following steps:
[0067] (1) Under the protection of nitrogen, mix ammonium hexachloroiridate, nickel nitrate hydrate, ammonium ferrous sulfate hydrate, ethanol and propionic acid; then reflux and stir for 5 minutes, then add ammonia water; after 10 minutes of reaction, cool naturally to room temperature, add Ethyl acetate coagulation and centrifugation; the centrifuged precipitate was washed with water and dispersed in ethanol to obtain a dispersion system; then manganese acetate, cobalt nitrate, and water were added, stirred for 10 minutes, added samarium samarium, stirred for 1 hour, and the support layer precursor was obtained;
[0068] (2) Add polyvinyl alcohol, hydrogen peroxide, and iron tetraphenylporphyrin to the dispersion system, stir at 50°C for 1 hour, then add 4,4-diaminophenylmethane, octamethylcyclotetrasiloxane, and stir under reflux 10 minutes, then concentrated to obtain ...
