Environmental-friendly quantum dot ripples prepared from the Couette flow of solution exhibiting strong laser polarizer ability
Herein, we fabricate a well-patterned semiconductor ripple structure via confined Couette flow of a quantum dot solution between two glass slides. This method is broadly applicable to diverse colloidal quantum dots, including environmentally friendly CuIn<sub>x</sub>Ga<sub>1-x</sub>S<sub>2</sub>, InP, and ZnSe nanocrystals. The resulting ripple structure demonstrates strong linear dichroism and polarization capabilities for lasers across a broad wavelength range (445-635 nm). Our work offers a convenient, solution-processable strategy for fabricating semiconductor-based polarizer films.
