Spectroscopic investigation of KBa2(PO3)5:Mn4+ activated glasses for plant cultivation applications

Abstract

Mn⁴⁺ is an impressive activator and sensitizer for luminescent material, which has been comprehensively investigated during the recent decades. In the present work, we give an account of the luminescence properties of Mn⁴⁺ activated KBa(PO₃)₅ glasses are successfully synthesized by using Melt quenching technique. SEM investigation confirms the proposed phosphite glass's morphological behaviour. A photoluminescence research showed that the proposed phosphor's emission peak was positioned in the far red emission area after being excited in the blue region. There are numerous indications that the peaks seen in the 650–750 nm region are helpful for growing plants. Therefore, the suggested glass sample is a promising contender for the use of cultivating far-red emitting plants.
