A series of novel lanthanum strontium aluminate phosphors, Ce3＋-doped LaSr2Alo（5–0.5x）Fx（LSAF） phosphors were success-fully synthesized using the high-temperature solid state synthesis procedure under reducing atmosphere （H2/N2=1/4）. The X-ray diffrac-tion pattern revealed that LSAF sample was a pure LaSr2Alo5 phase with a sintering temperature of 1250 °C. With the increasing amount of SrF2, the particle size of powders increased and the shape of particles changed more regularly. Being an orange/red emitting phosphors for orange and white light emitting diodes, LSAF：Ce3＋ could be effectively excited by blue lights with typical 4f→5d transitions of Ce3＋ ions. PL and PLE spectra showed inhomogeneous enlargement effects with the increase of F/o ratios, which suggested that electronega-tivity effect was promoted when F/o ratio increased. This was further confirmed by a red shift of PL spectra peak when F/o was in-creased. It can be concluded that the LSAF：Ce phosphors have the potential to meet the development of white light-emitting diodes.

稀土能够显著提升钢材的性能,是高品质钢中常见的合金元素之一。然而,由于稀土与o、S等杂质元素之间存在极强的亲和力,加入钢中后形成的高熔点、大尺寸夹杂物对浇铸工艺的顺行及产品质量均有严重危害。为了探讨不同铝含量对稀土耐热钢中非金属夹杂物类型及尺寸分布的影响,在利用优化的热力学模型进行模拟计算的基础上,设计并开展了高温试验。热力学计算结果表明,增大铝含量能够抑制钢中Ce_(2)o_(3)夹杂物的析出,同时促进CeAlo_(3)和Ce_(2)o_(2)S夹杂物的析出,根据钢液中Ce、Al、o及S含量的变化,总结了夹杂物转变的临界热力学条件,当铝质量分数为0.025%~0.065%时,满足w([Al])/w([Ce])为270,Ce_(2)o_(3)变质成CeAlo_(3);当铝质量分数为0.065%~0.17%时,满足w([S])/w([o])为10,Ce_(2)o_(3)转变为Ce_(2)o_(2)S。试验结果表明,在铈加入量一定的情况下,随着铝质量分数在0~0.3%范围内增大,不同试验钢中典型夹杂物的变化趋势为Ce_(2)o_(3)→Ce_(2)o_(3)+CeAlo_(3)→CeAlo_(3)+Ce_(2)o_(2)S,相应地,夹杂物的平均粒径由4.69μm降低至2.73μm。由夹杂物类型与尺寸之间关系的统计结果可知,尺寸较小的Ce_(2)o_(2)S的形成是导致夹杂物尺寸减小的主要原因之一;适当增大稀土耐热钢的铝脱氧强度,能够通过改变夹杂物类型的方式,有效细化钢中夹杂物的尺寸,有望改善稀土耐热钢的水口结瘤问题和产品质量。

There is currently no effective medical treatment for temporomandibular joint osteoarthritis(TMJ-oA) due to a limited understanding of its pathogenesis. This study was undertaken to investigate the key role of transforming growth factor-β(TgF-β)signalling in the cartilage and subchondral bone of the TMJ using a temporomandibular joint disorder(TMD) rat model, an ageing mouse model and a Camurati–Engelmann disease(CED) mouse model. In the three animal models, the subchondral bone phenotypes in the mandibular condyles were evaluated by μCT, and changes in TMJ condyles were examined by TRAP staining and immunohistochemical analysis of osterix and p-Smad2/3. Condyle degradation was confirmed by Safranin o staining, the Mankin and oARSI scoring systems and type X collagen(Col X), p-Smad2/3 a and osterix immunohistochemical analyses. We found apparent histological phenotypes of TMJ-oA in the TMD, ageing and CED animal models, with abnormal activation of TgF-βsignalling in the condylar cartilage and subchondral bone. Moreover, inhibition of TgF-β receptor I attenuated TMJ-oA progression in the TMD models. Therefore, aberrant activation of TgF-β signalling could be a key player in TMJ-oA development.
