Background:

Vertically aligned semiconductor nanorods are crucial for advanced optoelectronic devices.
Developing scalable and efficient methods for nanorod assembly remains a challenge.

Purpose of the Study:

To demonstrate a facile thermal annealing approach for assembling cadmium selenide (CdSe) nanorods into vertically aligned arrays.
To enable the solution-based fabrication of large-area films for optoelectronic applications.

Main Methods:

Utilized a thermal annealing process to control solvent strength for nanorod assembly.
Employed temperature gradients to disperse and reassemble CdSe nanorods (28 nm length) in solution.
Investigated the effect of solvent mixtures, nanorod concentration, and polydispersity on assembly.
