Application

Phosphors are solid inorganic crystalline materials that exhibit luminescence upon excitation. Applications of phosphors extend from bio-imaging/bio-sensors to X-ray detectors, fluorescent lamps, displays, and LEDs.[1][2][3][4][5] Our YYG series isiphor are yttrium garnet based yellow phosphors whereas the SGA series isiphor are silicate based green phosphors. These materials exhibit >90% quantum efficiency and are well suited for application in backlighting for liquid crystal displays and LEDs.

Hybrid metal halides containing perovskite layers have recently shown great potential for applications in solar cells and light-emitting diodes. Such compounds exhibit quantum confinement effects leading to tunable optical and electronic properties. Thus, broadband white-light emission has been observed from
Long persistent phosphors-from fundamentals to applications.
