Fluorescent Perovskite Composite Films
Core Skills:
Perovskite Processing • Thin Film Fabrication • Spin Coating • Annealing Optimization • Fluorescence Characterization • Surface Morphology Analysis • Optoelectronic Materials • Materials Formulation
Optimization:
Engineered and optimized fluorescent perovskite composite films through controlled formulation and processing design. Investigated the influence of spin-coating speed, material loading, and annealing conditions on film morphology, surface roughness, and optical performance.
Formulation and processing:
Identified an optimal formulation containing 75 wt% fluorescent additive, achieving significantly enhanced fluorescence output while reducing material usage. Optimized annealing conditions at 60 °C reduced film roughness by approximately 20% and improved fluorescence intensity, enabling smoother and more efficient optoelectronic film architectures.
