FIELD: construction industry.
SUBSTANCE: invention refers to manufacturing method of fluorescent ceramics having general formula Gd2O2S alloyed with the element chosen from the group consisting of Ce, Pr, Eu, Tb, Yb, Dy, Sm and/or Ho. Manufacturing method of fluorescent ceramic material includes the following stages: a) selection of powder-like pigment Gd2O2S alloyed with M, and M is at least the element chosen from the group containing Eu, Tb, Yb, Dy, Sm, Ho, Ce and/or Pr; at that, grain size of the above powder used for hot pressing is 1 mcm to 20 mcm, hot pressing and annealing. Hot pressing is performed at temperature of 1000°C to 1400°C and/or pressure of 100 MPa to 300 MPa, annealing - in vacuum at temperature of 1000 to 1400°C during 0.5-30 hours, and then -in the air at temperature of 700°C to 1200°C during 0.5-30 hours.
EFFECT: possibility of being used in ionising-radiation detectors.
