Sr 4‐ x S i 3 O 8 Cl 4 : x E u 3+ ( SSOC :Eu 3+ ) phosphors were successfully synthesized by hydrothermal method. The crystallization of this phosphor was analyzed by means of X‐ray diffraction patterns. The size and morphology were recorded using SEM patterns of samples. And the PLE and PL spectra were characterized by a PL spectrophotometer. Excited by 394 nm UV light, the intense red emission is recognized in SSOC :Eu 3+ phosphor and the main emission peak located at 620 nm. The influences of Eu 3+ concentration, pH value of reaction solution, and charge compensator on PL spectra of SSOC :Eu 3+ phosphors were investigated. The results revealed that this red phosphor had potential applications for white LEDs.
