When developing new methods for the diagnosis and treatment of cancer, the use of nanomaterials may be promising. One of the ways to improve and expand the fields of application of radiation and photodynamic therapy of cancer is the use of drugs containing nanosized phosphors. The aim of the work was to study the effect of the duration of hydrothermal synthesis and the conditions of rapid thermal annealing (RTA) on the Y 2 O 3 :Eu nanosized phosphors microstructure. The hydrothermal synthesis technique was carried out in two ways: chloride (precipitation from a chloride solution using NaOH and NH 4 OH precipitators) and acetate (decomposition of mixed acetate without a dispersant, as well as with PEG-200 and PEG-2000 dispersants). Hydrothermal synthesis was carried out at a temperature of 230 °C for 6–24 hours. Rapid thermal annealing was carried out at a temperature of 600–800 °C for 5–20 minutes. As a result of our work, the Y 2 O 3 :Eu nanosized phosphors which particle size does not exceed 200 nm is synthesized.
