Abstract
A laser sintering deposition method is provided for disposing lead selenide onto a substrate. The method includes: wet-milling a lead selenide ingot mixed with methanol into a colloidal slurry containing nanocrystals; separating the colloidal slurry into nanocrystal particles and the methanol; depositing the nanocrystal particles to a substrate; and emitting coherent infrared light onto the nanocrystal particles for fusing into a lead selenide crystalline film. Afterwards, the lead selenide film can be exposed to oxygen to form a lead selenite layer, and subsequently to iodine gas to produce a lead iodide layer onto the lead selenite layer.
