Liver cancer stands as a significant global health concern,contributing substantially to cancer incidence and mortality,particularly in Asian countries[1].Hepatocellular carcinoma(HCC)accounts for approximately 90%of all liver cancer cases and is characterized by a high-risk profile and a generally poor prognosis[2].To address advanced HCC,systemic therapy has been recommended,leading to the approval of a range of treatment regimens in clinical ***,first-line therapy involved the use of multitargeted tyrosine kinase inhibitors(TKIs)such as sorafenib or lenvatinib,while cabozantinib,ramucirumab.

近红外(NIR)荧光粉转换型发光二极管(pc-LED)具有尺寸小、效率高以及光谱易于调节的特点,在特种照明、传感、微型近红外光谱仪等各领域有很好的应用前景.目前,已报道的发射波长超过850 nm的近红外荧光粉的荧光热稳定性较差.在本项研究中,我们合成了一种立方相结构的Sc(PO_(3))_(3):xCr^(3+)(x=0,1,5,10,12,14,16,18 at%)荧光粉,其具有725–1150 nm的宽发射带,发射峰为875 nm,与之前报道的发射峰超过850 nm的荧光粉相比,其表现出优异的热稳定性,在423 K下,5 at%样品的积分发光强度保留了室温下的73.4%.通过对比研究立方相和单斜相Sc(PO_(3))_(3):Cr^(3+)荧光粉变温X射线衍射,发现立方相荧光粉优异的荧光热稳定性可能归因于高温下较小的键长和键角变化.利用该荧光粉制备的NIR pc-LED在150 mA电流驱动下,产生了26.62 mW的NIR辐射功率.驱动电流为10 mA时,最高电光转换效率为11.87%.这项工作为开发具有优异荧光热稳定性的Cr^(3+)离子掺杂近红外荧光粉提供了思路.
