Title: High spectral resolution of gamma-rays at room temperature by perovskite CsPbBr₃ single crystals

Abstract

Gamma-ray detection and spectroscopy is the quantitative determination of their energy spectra, and is of critical value and critically important in diverse technological and scientific fields. Here we report an improved melt growth method for cesium lead bromide and a special detector design with asymmetrical metal electrode configuration that leads to a high performance at room temperature. As-grown centimeter-sized crystals possess extremely low impurity levels (below 10 p.p.m. for total 69 elements) and detectors achieve 3.9% energy resolution for 122 keV ⁵⁷Co gamma-ray and 3.8% for 662 keV ¹³⁷Cs gamma-ray. Cesium lead bromide is unique among all gamma-ray detection materials in that its hole transport properties are responsible for the high performance. The superior mobility-lifetime product for holes (1.34 × 10^–3 cm² V^–1) derives mainly from the record long hole carrier lifetime (over 25 μs). Here, the easily scalable crystal growth and high-energy resolution, highlight cesium lead bromide as an exceptional next generation material for room temperature radiation detection.

Demonstration of Energy-Resolved γ-Ray Detection at Room Temperature by the CsPbCl₃ Perovskite Semiconductor

Journal Article He, Yihui ; Stoumpos, Constantinos C. ; Hadar, Ido ; ... - Journal of the American Chemical Society

The detection of gamma-rays at room temperature with high-energy resolution using semiconductors is one of the most challenging applications. The presence of even the smallest amount of defects is sufficient to kill the signal generated from gamma-rays which makes the availability of semiconductors detectors a rarity. Lead halide perovskite semiconductors exhibit unusually high defect tolerance leading to outstanding and unique optoelectronic properties and are poised to strongly impact applications in photoelectric conversion/detection. Here we demonstrate for the first time that large size single crystals of the all-inorganic perovskite CsPbCl₃ semiconductor can function as a high-performance detector for gamma-ray nuclear radiationmore »« less

Cesium lead bromide semiconductor radiation detectors: crystal growth, detector performance and polarization

Journal Article Toufanian, Reyhaneh ; Swain, Santosh ; Becla, Piotr ; ... - Journal of Materials Chemistry C

Cesium lead bromide (CsPbBr₃) is an upcoming semiconductor radiation detector that has the potential to match the detection properties of cadmium zinc telluride (CZT) and thallium bromide (TlBr). In this paper, we report on CsPbBr₃ gamma detectors with an uncorrected energy resolution of 2% at 662 keV with photopeak-to-Compton ratios as high as 14.3 and hole mobility-lifetime products (μτ_h) as high as 1.7 × 10^–2 cm² V^–1. Furthermore, we demonstrate that the processes employed for material purification and crystal growth of high-performing devices are scalable, and large (up to 65 mm in diameter) ultrahigh purity CsPbBr₃ crystals have been successfullymore »« less

An Effective Purification Process for the Nuclear Radiation Detector Tl ₆ SeI ₄

Journal Article Lin, Wenwen ; Kontsevoi, Oleg Y. ; Liu, Zhifu ; ... - Crystal Growth and Design

The semiconductor Tl6SeI4 was previously identified as a promising semiconductor for room temperature nuclear radiation detection. As the detection performance and carrier transport strongly depend on the concentration of impurity energy levels acting as scattering centers and carrier trapping, material purification is a crucial prerequisite step to obtain spectroscopic-grade detector performance. In this contribution, we present a highly efficient purification method using a bent ampule for evaporating Se, Tl2Se, and TlI precursors for Tl6Se4. On the basis of impurity analysis performed by glow discharge mass spectroscopy, the main impurities in Tl2Se were identified to be Pb, Bi, and Al, whilemore »« less

Perovskite CsPbBr₃ Single Crystal Detector for Alpha-Particle Spectroscopy.

Journal Article He, Yihui ; Liu, Zhifu ; McCall, Kyle M. ; ... - Nuclear Instruments and Methods in Physics Research. Section A, Accelerators, Spectrometers, Detectors and Associated Equipment

Here we report the first spectroscopic alpha particle detection based on CsPbBr₃ detectors with asymmetric contacts. The CsPbBr₃ single crystal was grown from melt using Bridgman method and then fabricated into detectors with different contacts. The In/CsPbBr₃/Au detector presented a low dark current (~100 nA/cm²) and temporal stable performance under high electric field (1000 V/cm). Such detector demonstrated excellent gamma ray resolving capability with a full-width at half maximum (FWHM) of ~5.9 keV for the ⁵⁷Co 122 keV γ ray. The CsPbBr₃ detector was capable of simultaneously resolving both the alpha particle (5.5 MeV) and γ ray (59.5 keV) peaksmore »« less

Gamma-ray Spectra from a 3x3 CsPbBr₃ Array

Journal Article Kim, Huicong ; Kargar, Alireza ; Cirignano, Leonard ; ... - IEEE Conference Record - Nuclear Science Symposium & Medical Imaging Conference (Online)

CsPbBr₃ is a promising semiconductor material for X- and γ-ray detection at room temperature due to a wide bandgap of 2.3eV, high stopping power, and relatively high mobility-lifetime products of electrons and holes, and the capability of growing large crystals. In this paper we report on fabrication and testing of a 3.8 mm thick, 3 X 3 array with 1.2 mm pitch. Raw¹³⁷Cs spectra were acquired with applied bias of 400 V, 500 V, and 600 V. Energy resolution of between 2 and 3 % FWHM at 662 keV was obtained from most pixels without any correction at room temperature.more »« less
