摘要：

We report a simple method for the fast synthesis of highly photoluminescent InP and InP/ZnS core-shell nanocrystals (NCs) covering a wide range of emissions from blue to the near infrared. Both InP and InP/ZnS NCs were prepared in one-step, in a one-pot reaction within 20 min using an InCl3 complex as a precursor and zinc carboxylate as an initiator and stabilizer. The quantum yields of the InP and InP/ZnS NCs were 30% and 60%, respectively. This new synthetic method allows fast and reproducible preparation of InP and InP/ZnS NCs with a quality comparable to that of the frequently used CdSe-based ones. It is anticipated that these particles can be used to replace CdSe for many applications.
