Background:

Colloidal nanocrystals offer high fluorescence quantum yield and tunable emission for light-emitting devices.
Integrating nanocrystals with polymer microcavities enables solution-based fabrication of plastic lasers and flexible optoelectronics.

Purpose of the Study:

To demonstrate lasing from polymer microcavities embedding solution-processable dot-in-rod (DiR) CdSe/CdS nanocrystals.
To develop a cost-effective fabrication method for plastic laser cavities.

Main Methods:

Fabrication of polymer dielectric mirrors using spin-coating of polyacrylic acid and poly(N-vinyl carbazole).
Tailoring the photonic band gap of the mirrors to match the emission spectrum of DiR nanocrystals.
Embedding DiR nanocrystals within the polymer microcavity via drop-casting and mirror pressing.

Main Results:

Achieved excellent overlap between the amplified spontaneous emission (ASE) band of DiRs and the cavity's photonic band gap.
Observed optically pumped lasing at 640 nm.
Demonstrated a low lasing threshold of approximately 50 μJ cm⁻².

Conclusions:

Solution-processable DiR nanocrystals can effectively function as gain media in polymer microcavities.
This approach offers a viable route for fabricating plastic laser cavities and flexible optoelectronic devices.
The results highlight the potential for advanced applications in smart lighting and sensing technologies.
