Transparent and brown La 2 O 3 −MoO 3 binary glasses were prepared in bulk form using a levitation technique. The glass-forming range was limited, with the primary composition being approximately 25 mol % La 2 O 3 . The 25La 2 O 3 −75MoO 3 glass exhibited a clear crystallization at 546 °C, while determining its glass transition temperature was difficult. Notably, despite its amorphous nature, the glass possessed a density and packing density comparable to those of crystalline La 2 Mo 3 O 12 . X-ray absorption fine structure and Raman scattering analyses revealed that the glass structure closely resembles La 2 Mo 3 O 12 due to the presence of isolated MoO 4 2− units, whereas disordered atomic arrangement around La atoms was confirmed. The glass demonstrated transparency ranging from 378 to 5500 nm, and the refractive index at 1.0 μm was estimated to be 2.0. The optical bandgap energy was 3.46 eV, which was slightly smaller than that of La 2 Mo 3 O 12 . Additionally, the glass displayed a transparent region ranging from 6.5 to 8.0 μm. This occurrence results from the decreased diversity of MoO n units and connectivity of Mo−O−Mo, which resulted in the reduced overlap of multiphonon absorption. This glass formation, with its departure from conventional glass-forming rules, resulted in distinctive glasses with crystallike atomic arrangements.

“…They are especially called conditional glass formers. 3 The glass-forming region of the binary system that includes conditional glass formers is generally narrow. Nevertheless, an additional small amount of network former oxide added to a binary system drastically improves the glass-forming ability.…”
