(TMT–TTF)[Pb2.6/3□0.4/3I2]3: a TTF-intercalated two-dimensional hybrid lead iodide: crystal structure and properties

A rare tetrathiafulvalene (TTF) derivative intercalated 2-D hybrid lead iodide with a partially oxidized TTF and Pb-vacancy in PbI2 was prepared. It exhibits a narrow band gap and high conductivity. The carrier density and photoelectric properties are first evaluated for a TTF-PbI compound.

The gamma camera

Nuclear cardiology imaging is traditionally performed on an Anger gamma camera. Its key component is a large, flat, circular or rectangular sodium iodide crystal, activated by non-radioactive thallium (NaI(Tl)). The side of the crystal facing the patient is covered with a lead collimator, while the side away from the patient is viewed by an array of photomultiplier tubes (PMTs). This chapter provides detail on the gamma camera, including information on crystals and collimators, PMTs, and electronics. Important measures of gamma camera performance parameters and quality control are covered in detail, and a section on dedicated solid-state cardiac gamma cameras is included.
