Green synthesis of K2TiF6:Mn4+ using KHF2 as accessory ingredient: A novel airtight solid-state strategy

A novel green airtight solid-state synthetic approach to produce K2TiF6:Mn4+ by using low-toxic KHF2 instead of high-toxic HF liquid was developed, the reaction mechanism schematic of the airtight solid-state strategy was discussed in detail.116
