Direct Synthesis of K2SiF6 : Mn4 + Red Phosphor from Crushed Quartz …
A simple method of synthesizing red phosphor is demonstrated. This method uses wet chemical etching of crushed quartz schist (QS) in a solution. The synthesized phosphor has particle sizes of less than with porouslike morphology. The photoluminescence and photoluminescence excitation spectroscopy show no clear …
