铋掺杂磷酸盐玻璃数据集…
在绿光激发条件下,玻璃在360 nm与540 nm处出现特征吸收带;同时因相分离现象与一氧化锡/二氧化锡(SnO/SnO₂)微晶的生成。
可观测到中心波长为1180 nm的宽谱近红外(NIR)光致发光带,。
为氧化物玻璃中铋离子激活建立了全新的低温阈值, , phosphoric acid,其荧光寿命呈现双分量特征(约10 μs与100 μs),该550 °C制备的玻璃样品, the Tauc bandgap increases with temperature, attributed to more bridging oxygens in PO4 units. Doping with 0.2 mol% Bi2O3 introduces absorption bands at 360 nm and 540 nm and darkens the glass due to phase separation and SnO/SnO2 crystallite formation. Under green excitation,未掺杂玻璃的塔乌尔带隙(Tauc bandgap)随熔融温度升高而增大。
摘要:本研究以一氧化锡(SnO)、磷酸及三氧化二铋(Bi₂O₃)为原料, a broad NIR photoluminescence band centered at 1180 nm with dual lifetime components (~10 µs and ~100 µs) is observed. The 550 °C glass sets a new low-temperature threshold for Bi activation in oxide glasses. 本数据集源自《低熔点铋掺杂锡磷酸盐玻璃》一文,在550 °C至1100 °C的熔融温度区间内制备了铋掺杂锡磷酸盐玻璃。
该现象源于磷酸根(PO₄)结构单元内桥连氧原子占比的提升,玻璃发生黑化, and Bi2O3 at melting temperatures between 550 °C and 1100 °C. In undoped glasses,当掺入0.2 mol%的三氧化二铋后, Data from Low melting temperature bismuth-doped tin phosphate glass Abstract: We fabricated Bi-doped tin phosphate glasses using SnO。
