Area of Science:

• Materials Science
• Solid-State Physics
• Detector Technology

Background:

• Omnidirectional X-ray detection is crucial for astrophysics and safety monitoring.
• Existing detectors face challenges in fabrication, omnidirectional response, and portability.

Purpose of the Study:

• To present a portable solid-state omnidirectional X-ray detector (ODXD).
• To utilize a novel spherical glass scintillator based on (CPTP)2MnBr4 for enhanced X-ray detection.

Main Methods:

• Fabrication of a spherical glass scintillator using a low-temperature melt-quenching process.
• Characterization of the (CPTP)2MnBr4 glass properties, including phase transitions and operational stability.
• Evaluation of the ODXD's omnidirectionality and X-ray response limit.

Main Results:

• The ODXD exhibits excellent omnidirectional response.
• Achieved an X-ray response limit of 0.49 µGyair s⁻¹, significantly lower than medical diagnostic rates.
• Demonstrated high sensitivity and operational stability due to the glass scintillator's properties.

Conclusions:

• The developed ODXD provides a portable and highly sensitive solution for omnidirectional X-ray detection.
• The molecular design of (CPTP)2MnBr4 enables efficient, low-temperature fabrication and stable operation.
• This work offers a viable approach for advanced sensing and photonic applications.
