Room temperature blue lasing of ZnSxSe1−x alloys by photopumping

Abstract
Photopumped lasing of ZnS0.05Se0.95 alloys grown by seeded physical vapor‐phase transport technique is observed at room temperature for the first time. This is achieved with the excitation photon energy tuned close to the band gap. The longitudinal lasing modes are well resolved. This work demonstrates that ZnSxSe1−x alloys can be used as an alternative to ZnSe in blue light‐emitting device fabrications.
