Embodiment 1
[0053] Example 1. Preparation of organic / metal nanowire heterojunction
[0054] Prepare 1 milliliter of 1 mmol per liter of triphenylpyridine iridium (Ir(ppy) 3 ) in dichloromethane solution; take 10 microliters of ethanol solution of silver nanowires with a mass percentage concentration of 0.1%, a length of 10-20 microns, and a diameter of about 200 nanometers, and add them to 2 milliliters of ethanol, and ultrasonicate at room temperature for 10 seconds; take the above prepared Ir(ppy) 3 100 microliters of the solution was added to the ethanol solution of silver nanowires to obtain a mixed system. After standing at room temperature for 2 hours, dendritic Ir(ppy) was obtained in solution 3 / Ag nanowire heterojunction. Take 30 microliters of the solution, drop it on the quartz substrate, dry at room temperature for 30 minutes, and obtain dendritic Ir(ppy) on the quartz substrate 3 / Ag nanowire heterojunction.

[0059] Example 3, Preparation of Organic / Metal Nanowire Heterojunction
[0060] Prepare 1 milliliter of 1 mmol per liter of triphenylpyridine iridium (Ir(ppy) 3 ) in chloroform solution; take 10 microliters of ethanol solution of silver nanowires with a mass percentage concentration of 0.1%, a length of 10-20 microns, and a diameter of about 200 nanometers, and add them to 2 milliliters of ethanol, and ultrasonicate at room temperature for 10 seconds; take the above prepared Ir(ppy) 3 100 microliters of the solution was added to the ethanol solution of silver nanowires to obtain a mixed system. Standing at 50°C for 2 hours, dendritic Ir(ppy) was obtained in solution 3 / Ag nanowire heterojunction. Take 30 microliters of the solution, drop it on the quartz substrate, dry at room temperature for 30 minutes, and obtain dendritic Ir(ppy) on the quartz substrate 3 / Ag nanowire heterojunction.
