ABSTRACT The authors have demonstrated white light emission of rare earth (RE)-free Mn-doped SnO-ZnO-P(2)O(5) glass. The RE-free glass shows white light emission with a high value of quantum efficiency (QE) comparable to conventional crystalline phosphor. It is notable that the high QE value is attained for RE-free transparent glass, and the broad emission can be continuously tuned by both the amount of activator and the composition of the glass. Since this glass possesses low-melting property, we emphasize that the glass phosphor will lead to the development of a novel inorganic white-light-emitting device in combination with a solid state UV light-emitting source.

    ABSTRACT: We have investigated the scintillation and dosimeter properties of Sn-doped 40Li2O.40B2O3.20SiO2 glasses and the Sn-free glass. The emission peak in the photoluminescence spectrum appeared at 350 nm and the quantum yield of the Sn-doped glasses was 20–50%, monotonically increasing with Sn concentration. The photoluminescence decay constants of the Sn-doped glasses were characterised by fast (a few ns) and slow (5–6 μs) components while, for the Sn-free glass, only the fast component was apparent. For the scintillation spectra under x-ray irradiation, the peak emission wavelength in the photoluminescence spectrum was similar for both Sn-free and Sn-doped glasses, suggesting that the absorbed energy was dominantly transferred to the host emission. In thermally stimulated luminescence, glow peaks of all glasses were observed at 250–300°C. We have also confirmed that the thermally stimulated luminescence for all of the glasses exhibited a proportionality to x-ray dose.

    ABSTRACT: Light emission in rare earth (RE)-free SnO-ZnO-P2O5 glasses is demonstrated. The RE-free transparent phosphate glasses show light emission with high quantum efficiency (QE) values, comparable to conventional crystalline phosphors, by excitation with deep-UV light. The broad emissions of the RE-free transparent glasses can be continuously tuned by both the amount of activator and the composition of the glasses, without reduction of the QE values. For future emitting devices, we believe that the low-melting glasses will constitute one of the most industrially favorable inorganic materials possessing transparency and emitting properties.

    ABSTRACT: As new light sources for next-generation illumination, white light-emitting diodes (WLEDs) have been extensively developed and are commercially available due to their excellent advantages, such as high efficiency, energy-saving, compactness, long operational lifetime and environmental friendliness. Currently, WLEDs with high color rendering are mainly based on wavelength conversion by one or more phosphor materials. In this review, the recent developments of phosphors for WLEDs were introduced combined with the relative work of our group. The common methods for generating white light for blue/ultraviolet (UV) WLEDs were summarized, including: (1) optimizing the commercially used phosphors; (2) developing some new phosphors based on UV LEDs chips; (3) realizing white light emission based on single host. Moreover, some typical new developed phosphors and their luminescence properties were introduced.
