Description
Summary:A system for studying the optical response of X-ray phosphors, considered as a constituent of co-mposite materials for X-ray photodynamic therapy, is described. The concept and main principles of X-ray photodynamic therapy are presented. The test results for the designed system are shown, and techniques of optimization of the signal-to-noise ratio by varying X-ray source parameters and the geometry of the experiment are discussed. Examples of XEOL measurements for concentrated powder samples and dilute samples in the form of colloidal solutions are considered.
