Embodiment 1
[0024] (1) Dissolve 2.23mg europium nitrate hexahydrate and 1.02mg dimethylamine hydrochloride in 1mL water to prepare solution A; dissolve 1.26mg oxalic acid dihydrate and 1.02mg dimethylamine hydrochloride in 1mL water to prepare into solution B;
[0025] (2) Set the spin-coating speed to 2000rpm, first spin-coat solution A on the SnO 2 On the electron transport layer, solution B was spin-coated immediately after solution A was spin-coated, rinsed with methanol after solution B was spin-coated, and then the ITO conductive glass substrate was placed on a heating plate at 70°C for 5 minutes to remove water and methanol. SnO 2 The Eu-MOFs interface modification layer is formed on the electron transport layer.
[0026] The XRD spectrum of the Eu-MOFs interface modification layer prepared in this example is consistent with the fitting curve of Eu-MOFs, indicating that the SnO 2 Eu-MOFs were successfully synthesized on the electron transport layer.
[0027] Referring to the pr...
Embodiment 2
[0029] (1) Dissolve 2.23mg europium nitrate hexahydrate and 1.02mg dimethylamine hydrochloride in 5mL water to prepare solution A; dissolve 1.26mg oxalic acid dihydrate and 1.02mg dimethylamine hydrochloride in 5mL water to prepare into solution B;
[0030] (2) Set the spin-coating speed to 4000rpm, first spin-coat solution A on the SnO 2 On the electron transport layer, solution B was spin-coated immediately after solution A was spin-coated, rinsed with methanol after solution B was spin-coated, and then the ITO conductive glass substrate was placed on a heating plate at 70°C for 5 minutes to remove water and methanol. SnO 2 The Eu-MOFs interface modification layer is formed on the electron transport layer.
[0031] The XRD spectrum of the Eu-MOFs interface modification layer prepared in this example is consistent with the fitting curve of Eu-MOFs, indicating that the SnO 2 Eu-MOFs were successfully synthesized on the electron transport layer.

Embodiment 3
[0034] (1) Dissolve 2.23mg europium nitrate hexahydrate and 1.02mg dimethylamine hydrochloride in 10mL water to prepare solution A; dissolve 1.26mg oxalic acid dihydrate and 1.02mg dimethylamine hydrochloride in 10mL water to prepare into solution B;
[0035] (2) Set the spin-coating speed to 3000rpm, first spin-coat solution A on the SnO 2 On the electron transport layer, solution B was spin-coated immediately after solution A was spin-coated, rinsed with methanol after solution B was spin-coated, and then the ITO conductive glass substrate was placed on a heating plate at 70°C for 5 minutes to remove water and methanol. SnO 2 The Eu-MOFs interface modification layer is formed on the electron transport layer.
[0036] according to figure 1 It can be seen that the XRD spectrum of the Eu-MOFs interface modification layer prepared in this example is consistent with the fitting curve of Eu-MOFs, indicating that the SnO 2 Eu-MOFs were successfully synthesized on the electron t...
