The photoluminescence spectra of the ZrSiO₄ and 3Y-TZP ceramics excited by laser irradiation with the wavelength of
325 nm are presented. The phase composition of the ceramics is determined by using X-ray diffraction measurements. The
spectra are recorded in visible region at the room temperature. The shape of the blue-green emission spectra depends on
technological parameters, such as the applied pressure and the sintering temperature. |
