Abstract
Official abstract text for this publication.
This invention is directed to photoluminescent compounds based on rhodamine dyes with red-shifted absorption and emission maxima 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 1, 2, 3, 4, 5, 6, 7, 8, 9, 10, or 11: 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, tetraflouroborate hexaflourophosphate, hypophosphite, phosphate, phosphite, cyanate, cyanide, isocyanate, thiocyanate, tetralkylborates, tetraarylborates 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 is in a form of a film. 5. The photoluminescent device of claim 3 , wherein said compound is a mixture of compound of formula 1 and compound of formula 2; or a mixture of compound of formula 5 and a compound of formula 6; or a mixture of a compound of formula 7 and a compound of formula 8; or a compound of formula 3, 4, 9, 10 or 11.
