Photoluminescence Detected Magnetic Resonance (PLDMR) is a powerful spectroscopic technique used primarily in the study of semiconductors, organic materials, and nanostructures. It combines photoluminescence (PL) and magnetic resonance to probe the spin-dependent processes that affect light emission in materials.
A 7230A lock-in amplifier plays a crucial role in Photoluminescence Detected Magnetic Resonance (PLDMR) by enabling the detection of very small changes in photoluminescence (PL) that are synchronized with the applied microwave modulation.
Lock-in Amplifier’s play in the PLDMR application
- The lock-in amplifier uses the microwave modulation frequency as a reference.
- It isolates the small PL changes that are synchronous with the microwave modulation.
- This allows detection of changes in PL as small as nanovolts, even in the presence of large background noise.
Through this application get more insights on the capabilities of Signal Recovery's 7230 Lock-in Amplifier and how it adds value to the PLDMR application.
