[Study of the photoluminescence spectra of laser dye impregnated in porous silicon].
We studied the photoluminescence (PL) of the compound films, which were made by implanting some laser dyes into the porous silicon films, and compared it with the PL of the laser dyes in other states. We also measured the PL of the compound films with different substrates. It was found that the spectra symmetry of the implanted laser dyes is better than that of the dyes in other states. The experimental results suggest that the PL of the compound films mainly comes from the monomers of the implanted laser dyes.
