Light emitting devices and applications thereof. The light emitting devices include a light emitting device having an active layer of a semi-conductor and a phosphor having the general formula Ca 1+x Sr 1−x Ga y In 2−y S z Se 3−z F 2 , wherein 0≦x≦1, 0≦y≦2 and 0≦z≦3. The phosphors are activated with an activator which may include dopants such as europium (Eu), cerium (Ce), praseodymium (Pr), terbium (Tb), ruthenium (Ru), erbium (Er), manganese (Mn) and mixtures thereof. |
