A Comparative Study on Photoluminescence Tuning and Chromaticity Control in Glycinium Trifluoroacetate (GTFA) and Melaminium Trifluoroacetate (MTFA)
S. Akshay Kalyan And N. Kanagathara
To develop functional organic materials for lighting, displays, sensors, inks, encryptions, and stimuli-responsive smart materials, it is important to tune the Photoluminesence (PL) color and control the emission chromaticity of the PL emissions. A combination of additive color mixing, the CIE 1931 x, y and color-matching functions allows emission spectra to be converted into numerical coordinates that define color. Glycine – a simplest amino acid and melamine – a nitrogen-containing heterocyclic organic compound react with trifluoroacetic acid, a reagent widely used in organic chemistry, forms glycinium trifluoroacetate (GTFA) and melaminium trifluoroacetate (MTFA) respectively. Photoluminescence studies have been performed on those two materials and the emission properties were compared. On comparison, GTFA and MTFA can gain new insights into their utility in controlling chromaticity and performing various functions.
