Core-shell doped QDs with the average size of 3.85 nm were obtained by using a one-pot synthesis followed by a hot injection with n-dodecanethiol(DDT) and oleylamine(OLA) as stabilizers in oil phase. Cu, Mn and Ag ions were introduced as single-dopant or co-dopants during the synthesis, providing an effective means to control the emission color of the QDs. The as-synthesized QDs showed photoluminescence emission ranging from green(530 nm) to near-red(613 nm), adjusted by doping components, dopant concentration, and Zn/In ratio. Importantly, quasi-white emission has been achieved by controlling the concentration of co-doped metal ions(Mn, Cu and Ag). The primary results demonstrated the promising potential of co-doped QDs as alternative materials for future high quality white LED applications.展开更多

The pathogenesis of the disease is incompletely under-stood;however, 50%to 70%of affected persons have an associated concomitant systemic disease such as inflammatory bowel disease (IBD) (1)Any site of the body can be affected;however, involvement of the oropharynx is rare. Here, we present a patient with disseminated PG with oropharyngeal involvement.展开更多

As an autosomal dominant pigment disorder, it usually occurs in post-pubertal individuals, and is seldom seen in children(2)However, a Chinese newborn with DDD was reported in 2008(3)In this review, we summarize features of DDD, emphasizing advances in genetics research and looking to the future for further understanding of its etiology and the development of therapeutic methods.展开更多
