摘要

研究了掺杂0.2 mol % TiO2、ZrO2、HfO2、Nb2O5、Ta2O5、MoO3或WO3的浮子型钠钙硅酸盐玻璃(SLS)的光学和结构性能。在紫外激发下,由于O2-的2p轨道跃迁到金属d0轨道,所有掺杂d0的玻璃都表现出集中在19,000 cm-1和25,000 cm-1 (400nm - 525nm)之间的宽带可见发射。掺杂导致紫外吸收边沿向较低能量偏移,掺杂玻璃的吸收边沿为2000 cm-1 (~20nm), MoO3的吸收边沿为4000 cm-1 (~40nm),低于相应的未掺杂玻璃。紫外-可见吸收和x波段EPR光谱分析证实,在所研究的玻璃中,Ti4+、Zr4+、Hf4+、Nb5+、Ta5+、Mo6+和W6+的氧化态出现了掺杂阳离子,尽管在g=1.92 (3.7T)处也观察到极低水平的Mo5+。将所研究的掺杂剂掺入SLS玻璃中,可能会在光伏(PV)应用中作为覆盖玻璃应用,为光伏单元中的聚合物和太阳能电池材料提供紫外线防护,同时通过吸收的紫外线光子的下转换/荧光再发射为可见光子,提高太阳能电池的效率,可用于太阳能电池材料的吸收和转换。

Optical and structural properties of d0 ion-doped silicate glasses for photovoltaic applications
Optical and structural properties of float-type soda lime silicate (SLS) glasses doped with 0.2 mol % TiO2, ZrO2, HfO2, Nb2O5, Ta2O5, MoO3 or WO3 have been studied. Under UV excitation all d0 doped glasses exhibit broadband visible emission centred between 19,000 cm-1 and 25,000 cm-1 (400nm – 525nm) due to a transition from the 2p orbital of O2- to the metal d0 orbital. Dopant additions lead to shifts in the UV absorption edge to lower energies, with doped glasses having an absorption edge 2,000 cm-1 (~20nm), and in the case of MoO3, 4,000 cm-1 (~40nm), lower than the corresponding undoped glass. Combined UV-Vis absorption and X-band EPR spectroscopy analyses confirm that dopant cations occur in the studied glasses in the expected oxidation states of Ti4+, Zr4+, Hf4+, Nb5+, Ta5+, Mo6+ and W6+, although very low levels of Mo5+ are also observed, as demonstrated by the EPR resonance at g=1.92 (3.7T). The incorporation of the studied dopants into SLS glasses may find applications as cover glasses in photovoltaic (PV) applications, providing UV protection of polymers and solar cell materials in PV units whilst enhancing solar cell efficiency through downconversion / fluorescence of absorbed UV photons with re-emission as visible photons, available for absorption and conversion by the solar cell material.

期刊介绍: Physics and Chemistry of Glasses accepts papers of a more purely scientific interest concerned with glasses and their structure or properties. Thus the subject of a paper will normally determine the journal in which it will be published.
