Embodiment 1
[0022] Step 1: Mix 40mL of benzene and 6mL of acetic acid to form a mixed solvent, add it to a three-necked flask, and under the protection of argon, add 1.00g of ammonium acetate (the amount of the substance is 13.0 mmol), 910mg of 4,5- Diazafluoren-9-one (the amount of the substance is 5.0 mmol) and 500 mg malononitrile (the amount of the substance is 7.5 mmol), install the water separator, heat and reflux at 80 ° C for 20 hours, cool to room temperature, and rotate The solvent was removed by evaporation, and the resulting residue was purified by chloroform column chromatography to obtain a yellow solid, which was analyzed by nuclear magnetic resonance, and the obtained spectrum was shown in figure 1 , it can be seen that the yellow solid is 9-dicyanomethylene-4,5-diazafluorene, and the yield is 61%. Melting point: 279-280 °C.
[0023] Step 2: In a one-necked bottle, dissolve 0.6 mmol Er(TTA)3·2H2O in 50 mL methanol solution, and dissolve 0.6 mmol yellow solid 9-dicyanometh...
Embodiment 2
[0027] Step 1 and step 2 are the same as in Embodiment 1.
[0028] Step 3: Prepare the 9-dicyanomethylene-4,5-diazafluorene metal erbium complex into a 1.1 mmol / L tetrahydrofuran solution, and spin-coat the solution on the surface of the silicon wafer to a thickness of 10 nm thin film, and then photolithography, HF etching, XeF2 etching, CO2 laser heating and reflowing to form a silicon oxide microring core optical microcavity, the specific steps are as follows image 3 shown.
[0029] Step 4: Fabricate an organic complex laser using a silicon oxide microring core optical microcavity assembly.
[0030] Laser test example
[0031] A single-mode optical fiber with a diameter of 125 μm is heated by hydrogen combustion, and then slowly drawn into a micro-fiber with a diameter of 1-2 μm, and the loss is controlled within 5%. Then put the silicon oxide microring core optical microcavity prepared in Example 1 on the three-dimensional piezoelectric console, precisely control its po...
