• Bandgap determination (Tauc plot)
• Quantum dot emission characterization
• Beer-Lambert quantification
• Aggregation monitoring

Usage Guidelines

Optical Analysis

1. LSPR Analysis

   • Monitor peak position and width
   • Track sensitivity to environment
   • Assess size and shape effects

2. Bandgap Determination

   • Apply Tauc plot method
   • Select direct/indirect transition
   • Report with uncertainty

3. Concentration Quantification

   • Apply Beer-Lambert law
   • Verify linear range
   • Account for scattering

Process Integration

• Multi-Modal Nanomaterial Characterization Pipeline
• Structure-Property Correlation Analysis
• Nanosensor Development and Validation Pipeline
