Thallium Halogenide Crystals: KRS-5

Description

KRS-5 is a thallium bromide (TlBr) crystal that is used in various applications, particularly in the field of radiation detection and imaging. It has a high atomic number and is highly efficient at absorbing gamma rays and other forms of ionizing radiation, making it useful in these applications.

KRS-5 has a wide transmission range, from the mid-infrared to the ultraviolet regions of the electromagnetic spectrum, and is transparent in the visible and near-infrared regions. This makes it useful in various optical applications, including lenses, prisms, and windows.

KRS-5 is particularly useful in gamma ray spectroscopy, where it is used as a detector material to measure the energy and intensity of gamma rays emitted by radioactive sources. It is also used in computed tomography (CT) scanners, where it is used as a detector material to produce high-resolution images of the human body.

One of the challenges with KRS-5 is that it is hygroscopic, meaning that it can absorb moisture from the air and degrade over time. To mitigate this, KRS-5 crystals are typically coated with a thin layer of a protective material to prevent moisture absorption.
