| Description |
The transmission spectra of GaSe crystals intercalated by CdTe nanoparticles (NPs) from aqueous colloidal solutions were investigated at 77 K in the range of GaSe excitonic absorption. Solutions of two types – yellow (with 1-2.5 nm NPs) and orange (with 2.5-3.5 nm NPs) – were used for the experiments. Essential GaSe optical density intensity growth in proportion to exposition time was observed after intercalation from yellow solutions up to 50 days. While the exciton peak position (near 2.1 eV) coincides both in “pure” GaSe and GaSe(CdTe) after intercalation from yellow solution, the shortwave shift is observed for GaSe(CdTe) intercalated from the orange solutions. The results are discussed in assumption of strain effect presence. |
