FLS1000 Photoluminescence Spectrometer

The FLS1000 Photoluminescence Spectrometer establishes excellence in steady-state and time-resolved photoluminescence spectroscopy, serving as the preferred instrument for both sophisticated research and standard laboratory procedures.

Key Technical Features:

• Ultimate Sensitivity: Industry-leading signal-to-noise ratio of 35,000:1 (water Raman SQRT method) ensures detection of extremely weak photoluminescence signals.
• Modular Architecture: Configurable with a selection of light sources, detectors, and sample holders to meet specific research requirements, enabling optimal system customization.
• System Upgradability: Designed for future expansion with additional modules to accommodate evolving research needs, safeguarding investment and maintaining cutting-edge capabilities.
• Extended Spectral Range (NIR & MIR): Offers a range of infrared detector options for characterizing NIR and MIR emitters with sensitivity extending to 5500 nm.
• Automated Operation: Features advanced Fluoracle® software for comprehensive experiment control, data acquisition, analysis, and time-saving automation functionalities.
• Micro-Spectroscopy Capability: Transformable into a high-performance photoluminescence microscope via the MicroPL Upgrade, enabling high-resolution mapping of microscopic samples.

This modular system provides precise measurements across a wide spectral range, spanning the ultraviolet to the mid-infrared (up to 5,500 nm), and measures lifetimes from picoseconds to seconds. It also delivers highly accurate absolute photoluminescence quantum yield measurements, with versatile upgrade options available at initial purchase or for future integration as your research progresses.

Regardless of your application, the FLS1000 enables luminescence spectra and kinetics measurements with exceptional accuracy through advanced sources, detectors, and acquisition methodologies. Its spacious sample chamber readily accommodates a wide array of sample accessories.

All instrument functions are seamlessly controlled by Fluoracle^®, a comprehensive software suite for integrated data acquisition and analysis.

Steady State

Excitation-Emission Maps (EEM)

Besides standard excitation and emission spectra, Fluoracle can perform synchronous scans, excitation-emission maps (EEMs), and kinetic scans at a single or multiple wavelengths. The example shows an EEM acquired with a camera, which provides maximum acquisition speed acquiring a full emission spectrum in a single shot.

Time Resolved – TCSPC

Exponential Decay Analysis

Acquisition and analysis of time-resolved fluorescence is easy with the FLS1000. Fluoracle offers easy measurement wizards for time-correlated single photon counting (TCSPC), as well as analysis tools for exponential decay fitting.

Time Resolved – MCS

Time-Resolved Emission of Metal Halide Hybrids

The photoluminescence emission lifetime of metal halide hybrids extends over a large time range from nanoseconds to milliseconds. In this case the method of choice for time-resolved measurements is the Multichannel Scaling (MCS), which provides speed of measurement with photon-counting sensitivity.

PLQY

Absolute Quantum Yield of PbS Quantum Dots

The QYPro Integrating Sphere enables easy measurements of absolute photoluminescence quantum yield (PLQY) in the visible and NIR range. This method is more accurate than the relative QY approach, does not require a QY standard and is readily applicable to liquids, films and powders.
