Cd1-xMnxTe is a promising material that has been introduced as a potential successor for the popular Cd1-xZnxTe material in the field of room-temperature gamma-ray detection. In this work, we demonstrate a planar array on a 5 mm thick Cd1-xMnxTe detector with spectroscopy performance similar to that of industrial Cd1-xZnxTe devices of the same thickness. The uniformity of Cd1-xMnxTe was theoretically predicted and experimentally demonstrated to be superior to that of Cd1-xZnxTe due to a better solubility of manganese. The main challenge until now was to exhibit large area, thick Cd1-xMnxTe arrays with satisfactory spectroscopy performance. In this Letter, static as well as spectroscopic properties of thick Cd1-xMnxTe devices are compared to those of conventional Cd1-xZnxTe detectors, grown by the same technology (horizontal Bridgman).

Fluorescence imaging is a promising method widely used for the evaluation of the biodistribution and accumulation of various fluorescent agents cross-linked to the drug for effective therapy control. This work presents the methods for the functionalization of nanomaterials to provide them with fluorescent properties. The first of these methods is a unique technology for producing porous silicon with fluorescent properties. The second approach demonstrates linking of the fluorophores to inorganic nanoparticles (NP) using a spacer molecule ending with a functional group. For all these examples of fluorophores, biodistribution studies were performed with the fluorescent imaging system IVIS Lumina LT III (PerkinElmer, USA). It was noted that the size of particles and the method of their injection affect the distribution and accumulation in organs. The resulting materials can be used to develop platforms for theranostics.
