Description
Key Advantages
High Refractive Index (2.1)
Enables efficient light coupling with optical fibers and photodetectors, minimizing signal loss in fiber laser systems and radiation detectors. This high index is particularly valuable for fiber-based applications, where optimal light confinement enhances laser efficiency and detector sensitivity.
Exceptional Light Yield (60,000 ph/MeV)
One of the highest photon yields among scintillators, emitting ultraviolet-blue light (380 nm) with intensity proportional to incident radiation energy. This ensures superior signal-to-noise ratios, enabling precise energy measurement and high-resolution imaging in low-dose applications.
Superior Energy Resolution (<4.5% @ 662 keV)
Combined with its high light yield, CeBr₃ offers outstanding ability to distinguish between gamma ray energies—critical for identifying specific isotopes in nuclear medicine, environmental monitoring, or security screening.
Fast Decay Time (20 ns)
Minimizes signal pile-up in high-count-rate scenarios, such as busy radiation monitoring stations or fast-scan detectors. This speed is essential for real-time applications, where rapid signal processing reduces data latency.
High Sensitivity
Efficiently detects a broad range of radiation energies (from keV to MeV), making it suitable for diverse applications—from gamma spectroscopy to X-ray imaging.
