论文摘要
首次制备了荧光磷酸玻璃中的量子点CSPBX_3（X = Cl，Br，I）。通过两种方法沉淀样品：（i）通过冷却玻璃熔体和（ii）玻璃的热处理过程中的自结晶。通过调整冷却速率和热处理条件来实现CSPBX_3量子点的受控形成。 X射线衍射数据已确认CSPBCL_3（BR_3，I_3）量子点的形成。结果表明，CSPBX_3（X = Cl，i）量子点是在立方修改中形成的，而Orthorhombic One中的CSPBBR_3。量子点的光致发光具有高强度，量子产率为45-50％和窄带发射。两种阴离子（Cl/br和br/i）的结合引入导致了两种类型的量子点的同时形成，并指示了阴离子交换的难度。
For the first time the quantum dots CsPbX_3 (X=Cl, Br, I) in the fluorophosphate glasses were prepared. The samples were precipitated by two methods:(i) through self-crystallization during cooling of the glass melt and (ii) heat treatment of the glass. Controlled formation of CsPbX_3 quantum dots was realized by adjustment of cooling rate and heat-treatment conditions. The X-ray diffraction data was confirmed CsPbCl_3(Br_3, I_3) quantum dots formation. It was shown that, CsPbX_3 (X=Cl, I) quantum dots are formed in a cubic modification, while CsPbBr_3 in orthorhombic one. The photoluminescence of quantum dots have high intensity with quantum yield 45-50% and narrow band emission. The combined introduction of two anions (Cl/Br and Br/I) led to the simultaneous formation of two types of quantum dots, and indicates the difficulty of the anion exchange.
