Abstract
A process for preparing a single source solid precursor matrix for semiconductor nanocrystals having the steps of: mixing 0.1-1 Molar of an aqueous/non-aqueous (organic) solution containing the first component of the host matrix with 0.001-0.01 Molar of an aqueous/non-aqueous solution containing the first dopant ions, which needs in situ modification of valency state, dissolving 10-20 milligram of an inorganic salt for the in situ reduction of the first dopant ion in the solution, addition of 0.001-0.01 Molar of an aqueous/non-aqueous solution of an inorganic salt containing the dopant ions which do not need modifications of their valency state, addition of 0.1-1 Molar of an aqueous/non-aqueous solution of an inorganic salt containing the second component of the host material, addition of 5-10% by weight of an aqueous solution containing a pH modifying complexing agent, to obtain a mixture, and heating the mixture to obtain a solid layered micro-structural precursor compound.
