FIG. 1.

(a) Optical photograph of a BP3T thin-plate-like crystal (taken under a dark field with a UV light illumination because the thinness of the crystal prevented photographing it under a bright field). Inset structure of BP3T. (b) Scanning electron microscope image of the crystal.

FIG. 2.

(a) Laser-induced PL spectra of BP3T single crystals as a function of incident laser power density. (b) Laser oscillation spectrum of BP3T crystal with a pair of parallel facets that worked as an optical resonator at the pumping light intensity of .

FIG. 3.

Photopumping intensity dependence of peak intensities (엯) and FWHM values (●) of PL spectra of BP3T crystals.

characteristics of several BP3T single crystal devices with different metal cathodes. The two characteristics for the Au cathode device are shown; open triangles represent the positive biased characteristics for the deposited Au cathode, while closed triangles represent those of the adhesion Au anode. Inset (upper left): EL spectrum of BP3T single crystal device. Inset (lower right): Double logarithmic plot of current density vs EL intensity characteristics of the BP3T single crystal device with a Li cathode.
