A bifluorene analogue, T2N, containing a pyridyl moiety serves as both a host and an efficient electron-transporting material that is compatible with various heavy metal-containing red (Ir, Ru, Os, and Pt) and green (Ir) phosphors for highly efficient phosphorescent OLEDs possessing simple device architectures.

The title compound, [Na(2)(C(10)H(16)Cl(3)N(3)O(4)P)(2)(H(2)O)(2)](n), can be considered as a two-dimensional coordination polymer in which one-dimensional chains are connected to each other by inter-molecular C-H⋯O hydrogen bonds involving the water mol-ecules. The Na(I) ion is five-coordinated in a distorted trigonal-bipyramidal geometry. The connection between the two Na(I) ions is facilitat...

The traditional solid-state technique was used to create LaBSiO5 phosphors doped with Ce3+ and Tb3+ at 1,100 °C. These phosphors' phase purity luminous characteristics are looked at. Under ultraviolet (UV) light stimulation, LaBSiO5: emit bright green light, whereas samples incorporated blue-violet light. With UV ray as well illumination. 5d-4f shift for is responsible the radiation, while 5D4→...
