This innovative process is an automated method and system for analyzing photo-luminescence (P-L) intermittency, or "blinking," in semiconductor quantum dots (QDs). This method involves exciting single QDs, collecting image and raw blinking movies, and extracting P-L blinking trajectories from this raw data. It uses an Intensity Histogram Dependent Thresholding (IHDT) technique for grey-free two-state blinking analysis and conventional FT techniques to classify blinking characteristics. The system automates the detection and analysis processes, enabling efficient and detailed statistical analysis of QDs' blinking behaviors, which is crucial for understanding material quality and improving opto-electronic device performance.

Quantum Dots (QDs) are tiny particles with great potential for use in technologies like displays and medical imaging. However, their inconsistent light emission, known as blinking, poses a significant challenge. Traditional methods to analyze this blinking are unreliable and labor-intensive, often misclassifying light levels and requiring extensive manual work. This makes it difficult to study large numbers of QDs efficiently. We need an automated, reliable method to accurately analyze QD blinking, eliminate errors, and handle large datasets quickly, ensuring consistent and precise results.
