Abstract
Official abstract text for this publication.
This invention is directed to photoluminescent compounds based on rhodamine dyes with green emission and uses thereof for photoluminescence based devices.
First claim
Opening claim text (preview).
What is claimed is: 1. A photoluminescent compound represented by the structure of formula 8, 9, 10, 11, 12, 15 or 16: wherein X − is an anion. 2. The photoluminescent compound of claim 1 , wherein said anion is a sulfate, chloride, bromide, iodide, perchlorate, nitrate, trifluoroacetate, hydroxide, hydrosulfide, sulfide, nitrite, carboxylate, dicarboxylate, sulfonate, tetrafluoroborate, hexafluorophosphate, hypophosphite, phosphate, phosphite, cyanate, cyanide, isocyanate, thiocyanate, tetralkylborate, tetraarylborate or chromate. 3. A photoluminescent device comprising a color-conversion-layer comprising a photoluminescent compound according to claim 1 . 4. The photoluminescent device of claim 3 , wherein said color-conversion-layer comprises a compound of formula 8, 9, 10, 11, 12, 15, 16 or combination thereof. 5. The photoluminescent device of claim 3 , wherein said color-conversion-layer is in a form of a film. 6. The photoluminescent device of claim 3 , wherein said device includes a color conversion film comprising said color conversion layer. 7. The photoluminescent device of claim 3 , wherein the color conversion layer in said device comprises an emission peak between 520-560 nm and FWHM between 30-55 nm.
