The synthesis and properties of Ca Sc Si O :Ce (CSSG) phosphor are utilized for the development of human-centric lighting light-emitting diodes (HCL-LEDs).

In this study, cerium ion (Ce )-doped calcium scandium silicate garnet (Ca Sc Si O , abbreviated CSSG) phosphors were successfully synthesized using the sol-gel method. The crystal phase, morphology, and photoluminescence properties of the synthesized phosphors were thoroughly investigated. Under excitation by a blue light-emitting diode (LED) chip (450 nm), the CSSG phosphor displayed a wide emission spectrum spanning from green to yellow.

Analysis of the structure and luminescence properties of Zn GeO :Eu according to Judd-Ofelt theory.

The preparation and characteristic of nanorod-like Zn GeO doped with Eu or zinc germanate (ZGO):xEu (x = 0 ÷ 0.05), which was synthesized using the hydrothermal method, are described. The influence of Eu -doping ions on the structure and the optical properties of ZGO was also investigated.

Characterization of structural and optical properties of Mn -doped Zn GeO nanorods as an efficient green phosphor for solid-state lighting.

A series of Mn -doped zinc germinate ZGO:xMn (x = 0-0.05) nanorods was synthesized successfully using a hydrothermal method. XRD revealed that crystal phases of the ZGO:xMn were rhombohedral and in the R-3 space group.
