Ion-beam luminescence of thin-film CdS on glass formed by pulsed-laser deposition

CdS thin films on glass have been produced with infrared pulsed-laser deposition. Three emission bands, in the green, yellow, and red spectral regions were observed in ion-beam luminescence (IBL) spectra of these as-deposited films. The temperature dependence of the IBL spectra of the films was investigated. The variations of the spectra with various species of implanted ions were also studied. It was found that for light ions (${\mathrm{H}}^{+}$ or ${\mathrm{H}}_2^{+}$ ) the intensity of all the luminescence bands was increased by decreasing the sample temperature. The relative intensities of the peaks changed with temperature so that the overall peak shapes appear to move as the temperature decreased. Comments on the origin of the signals are included.
