Study of the photoluminescence kinetics of heterogeneous nanostructured Pb0.30Cd0.70I2 solid solutions

Nature of Radiative Recombination Processes in Layered Heterogeneous PbCdI2 Thick Films: Promising Scintillator Materials

“…It should be noticed that since the investigated films were obtained by drying a solution of PbI 2 and CdI 2 in absolute N,N-dimethylformamide, the residual solvent created a thin layer on the surface of the films interfering with direct observation of small PbI 2 nanoparticles as it had been observed earlier for the bulk PbCdI 2 crystals [14].…”

“…Layered PbI 2 semiconductors are promising materials, since they have a high potential for the development of noncooled detectors for both -and X-radiation [4][5][6][7][8]. Recently, it was shown that the alloys based on PbI 2 , namely, PbCdI 2 crystals, are nanostructured bulk solids, where PbI 2 nanoclusters (NCLs) are naturally formed in CdI 2 matrix during the growth process [9][10][11][12][13][14]. The bulk PbI 2 crystal is a direct bandgap semiconductor with an energy gap of about 2.5 eV [15][16][17].…”
