Abstract
The present disclosure provides a method of preparing a chalcogen containing solution that is hydrazine free and hydrazinium free, wherein the method comprises: providing a predetermined amount of elemental chalcogen; providing a predetermined amount of elemental sulfur; providing an amine solvent; and combining the predetermined amount of elemental chalcogen and the predetermined amount of elemental sulfur in the amine solvent, thereby dissolving the elemental chalcogen and the elemental sulfur in the amine solvent. The chalcogen containing solution can advantageously be used as a precursor for the formation of a chalcogen containing layer on a substrate.

A method of preparing a chalcogen-containing solution that is hydrazine free and hydrazinium free, the method comprising:
- providing a predetermined amount of elemental chalcogen;
- providing a predetermined amount of elemental sulfur;
- providing an amine solvent;
- and
- combining the predetermined amount of elemental chalcogen and the predetermined amount of elemental sulfur in the amine solvent, whereby the elemental chalcogen and the elemental sulfur are dissolved in the amine solvent, thereby forming a chalcogen-containing solution that is hydrazine free and hydrazinium free.
