Room-Temperature Photoluminescence in Layered ?-GaSe, GaSe0.9S0.1, GaSe0.8S0.2 under Pressure

Transmission, reflection and thermoluminescence studies on GaS0.75Se0.25 layered single crystals

“…Due to their tunable compositions with a wide variety of optical and electrical properties, they are used especially in optoelectronic technology. GaS x Se 1Àx mixed ternary crystals are formed from GaSe and GaS without restrictions on the concentration of the constituent compounds (0 x 1) [1][2][3]. Band gap energies of the series cover a wide range of the visible spectrum by adjusting the composition of the constituent compounds in the desired way.…”

Analysis of glow curve of GaS0.5Se0.5 single crystals

“…GaS x Se 1-x mixed crystals are formed from GaSe and GaS without restrictions on the concentration of the constituent compounds (0 ≤ x ≤ 1) [11][12][13]. Taking into consideration the technological applications of GaSe and GaS, GaS x Se 1-x mixed crystals can be important candidate to be used in the fabrication of long-pass filter, light emitting devices and optical detecting systems.…”

Selective Raman modes and strong photoluminescence of gallium selenide flakes on sp2 carbon

“…4 Recently, some interesting theory results such as a valence band structure with an inverted sombrero shape, and other electronic and optical properties of GaSe were reported revealing the potential for optoelectronic devices 5,6 and even as a photocatalyst for water splitting. [10][11][12] However, only very recently, spatial inhomogeneities were found in the PL spectra of GaSe surfaces. 8,9 The photoluminescence (PL) and Raman spectra of bulk GaSe were reported very early.…”
