Ho2 Ge2 O7
semiconductor· Ho2 Ge2 O7
Ho₂Ge₂O₇ is a rare-earth germanate ceramic compound combining holmium (a lanthanide) with germanium oxide in a pyrochlore or related crystal structure. This material is primarily of research interest for its potential in photonic, thermal, and radiation-resistant applications, rather than a widely commercialized engineering material. The holmium-germanate system is investigated for scintillation detection, luminescence, thermal barrier coatings, and nuclear fuel waste immobilization, where its rare-earth dopant effects and ceramic durability offer advantages over conventional oxides.
