Abstract

Intense infrared emission peaking at a wavelength of 1.35 {mu}m has been observed in Ge-doped ZnSe crystals at low temperatures. The emission was particularly strong in the crystals doped with Ge in Se atmosphere and was then rapidly quenched. The emission was accompanied by a characteristic additive absorption band centered around a wavelength of 500 nm, which showed a partial but distinct metastable change upon light irradiation. The excitation spectrum and the preparation conditions of the infrared emission corresponded to those of electron spin resonance signals, owing to isolated, trivalent Ge ions in ZnSe. The nature and the possible applications of the emission are discussed. (c) 2000 American Institute of Physics.

Properties of ZnSe crystals doped with phosphorus

Journal Article Makhnii, E V ; Mel`nik, V V - Inorganic Materials

Preparation of ZnSe crystals that would exhibit hole conduction and dominant edge luminescence at 300 K is vital for optoelectronic applications. To solve this problem, several interrelated methods for producing p-type conductivity in ZnSe are now used: ion implantation of Group I and V elements, annealing in elemental Se vapor molecular beam epitaxy, and annealing in Se melt with Li additions. Doping of n-type ZnSe crystals with acceptor impurities via high-temperature diffusion is not utilized for this purpose, first, because it provides relatively low hole conductivity and, second, because the resultant crystals exhibit mainly long-wavelength, red-orange emission at 300 K.more »« less
Raman and photoluminescence studies on intrinsic and Cr-doped ZnSe single crystals

Book Rai, B K ; Bhaskar, S ; Bist, H D ; ...

Single crystals of ZnSe, with varying amounts of Cr doping have been studied using Raman and photoluminescence (PL) spectroscopy. The Cr-doped samples show the existence of a coupling mechanism of longitudinal optical (LO) phonons of ZnSe with hole-plasmons. The dependence of intensity ratio of LO and transverse optical (TO) mode on temperature and excitation wavelength, has been attributed to the interaction of the field of LO phonons with the surface electric field in the depletion layer. The interaction of discrete phonons with the electronic continuum of conduction band in ZnSe is responsible for the shift of Raman peaks. The largemore »« less
Absorption spectra and nonlinear transmission (at λ = 2940 nm) of a diffusion-doped Fe{sup 2+}:ZnSe single crystal

Journal Article Bufetova, G A ; Gulyamova, E S ; Il'ichev, N N ; ... - Quantum Electronics (Woodbury, N.Y.)

Transmission spectra of a ZnSe sample diffusion-doped with Fe{sup 2+} ions have been measured in the wavelength range 500 – 7000 nm. A broad absorption band in the range 500 – 1500 nm has been observed in both doped and undoped regions of the sample. This band is possibly due to deviations from stoichiometry in the course of diffusion doping. The transmission of the Fe{sup 2+}:ZnSe sample at a wavelength of 2940 nm has been measured at various dopant concentrations and high peak pulse intensities (up to 8 MW cm{sup -2}). The samples have been shown to be incompletely bleached:more »« less

Core–shell interaction and its impact on the optical absorption of pure and doped core-shell CdSe/ZnSe nanoclusters

Journal Article Wang, Xinqin ; Cui, Yingqi ; Zeng, Qun ; ... - Journal of Chemical Physics

The structural, electronic, and optical properties of core-shell nanoclusters, (CdSe){sub x}@(CdSe){sub y} and their Zn-substituted complexes of x = 2–4 and y = 16–28, were studied with density functional theory calculations. The substitution was applied in the cores, the shells, and/or the whole clusters. All these clusters are characterized by their core-shell structures in which the core-shell interaction was found different from those in core or in shell, as reflected by their bondlengths, volumes, and binding energies. Moreover, the core and shell combine together to compose a new cluster with electronic and optical properties different from those of separated individuals,more »« less

The photoluminescence and optical constant of ZnSe/SiO{sub 2} thin films prepared by sol-gel process

Journal Article Haiqing, Jiang ; Xi, Yao ; Jun, Che ; ... - Materials Research Bulletin

In this paper, ZnSe/SiO{sub 2} thin films were prepared by sol-gel process. X-ray diffraction results indicate that the phase structure of ZnSe particles embedded in SiO{sub 2} thin films is sphalerite (cubic ZnS). The dependence of ellipsometric angle {psi} on wavelength {lambda} of ZnSe/SiO{sub 2} thin films was investigated by spectroscopic ellipsometers. The optical constant, thickness, porosity and the concentration of ZnSe/SiO{sub 2} composite thin films were fitted according to Maxwell-Garnett effective medium theory. The thickness of ZnSe/SiO{sub 2} thin films was also measured by surface profile. The photoluminescence properties of ZnSe/SiO{sub 2} thin films were investigated by fluorescence spectrometer.more »« less
