FIG. 1.

Experimental PL spectra of as-prepared and irradiated multilayered samples at . As-prepared samples were irradiated with a diode pumped solid state laser of wavelength and a power density of up to at room temperature to produce photoinduced interdiffusion between the multilayers.

FIG. 2.

Optical absorption edges of homogeneous -thick (1) (4) and the same for as prepared (2) and irradiated (3) multilayered samples.

Image of FIG. 3.
FIG. 3.

Deconvoluted experimental PL spectra of (a) ML1, (b) I-ML1, (c) ML2, and (d) I-ML2. The experimental spectra are represented by symbols “엯;” deconvoluted spectra are represented by curves 1,2,3,4,5. The resultant of the deconvoluted spectra is represented by curve 6.
