Luminescence Properties of Oxyfluoride Glass and Glass Ceramic Doped with Y3 + Ions

 Oxyfluoride glass ceramics containing CaF2nano-crystals doped with Y3+ ions were prepared by one-step crystallization of SiO2- Al2O3- CaO- CaF2 glasses at different temperatures. X- ray diffraction (XRD) results have revealed that CaF2 was the only precipitated crystalline phase in glass ceramic samples. According to the XRD results, a glass ceramic was selected as the best sample in order to ...

Photodegradation of HMX and RDX in the Presence of Nanocatalyst of Zinc Sulfide Doped with Copper

Nanoparticles of zinc sulfide as undoped and doped with copper were used as photocatalyst in the photodegradation of HMX (octahydro-1,3,5,7-tetranitro-1,3,5,7-tetrazocine) and RDX (hexahydro-1,3,5-trinitro-1,3,5-triazine) as nitramine explosives under UV and Vis irradiations. Photoreactivity of doped zinc sulfide was varied with dopant, mole fraction of dopant to zinc ion, pH of solut...

Enhancing luminescence in lanthanide-doped upconversion nanoparticles.

The enthusiasm for research on lanthanide-doped upconversion nanoparticles is driven by both a fundamental interest in the optical properties of lanthanides embedded in different host lattices and their promise for broad applications ranging from biological imaging to photodynamic therapy. Despite the considerable progress made in the past decade, the field of upconversion nanoparticles has bee...
