The influence of the Sc3+ dopant on the transmittance of (Y,Er)(3)Al5O12 ceramics // DALTON TRANSACTIONS. - 2021. - DOI 10.1039/d1dt02419a
Abstract: High erbium content yttrium aluminum garnet (Er:YAG) and yttrium scandium aluminum garnet (Er:YSAG) ceramics have been fabricated from Er:YAG and Er:YSAG powders, respectively. The powders have been synthesized via a reverse precipitation technique, processed by uniaxial pressing followed by cold isostatic pressing, and sintered in a vacuum. TEOS (tetraethoxysilane) was used as a sintering additive. After vacuum sintering, all of the samples were processed by annealing in air to increase the transmittance and polished on both sides. The influence of the Sc3+ content and the synthesis conditions on the microstructure and optical transparency of the Er:YAG and Er:YSAG ceramics have been investigated in detail. It has been found that changing Al3+ for the bigger Sc3+ ion leads to the transmittance increasing to up to 60% at a wavelength of about 1500 nm
