Measurement principles, clearly explained
Theory
Explore the scientific foundations of absolute luminescence and time-resolved photoluminescence—from photon balance and quantum yield to carrier dynamics, QFLS and lifetime analysis.
01
Absolute PL
Absolute photoluminescence and electroluminescence measurements quantify luminescence efficiency and reveal the internal voltage potential of semiconductor materials and devices under optical or electrical excitation.
