چکیده
The study investigated the photoluminescent properties of undoped and rare-earth element erbium - doped solid solutions GaS1-xSex0.1аt% irradiated with gamma-quanta. Erbium doping reduces photoluminescence intensity in solutions. After irradiation Dg= 300-1000Gy, increases. An increase is explained by a decrease concentration centers responsible for fast recombination channel associated lattice defects. At T=77K, due to decay bound Frenkel pairs, Si Vs appear sulfur sublattice. defects are green luminescence band. redistribution range 0.520 0.600 µm transfer energy activated crystals. performed investigations allow us conclude that leads appearance series emission lines visible region spectrum.

Roots appear in quanta: exercise solutions
Herein are solutions to the exercises given in [1]. Let K be a field, and f(X) ∈ K[X] an irreducible polynomial. The root quantum number rK(f) is the number of roots of f in the stem field K(α), where α is an arbitrary choice of root of f . It was shown that rK(f) is well-defined and divides the degree of f . We start by establishing the connection with Galois theory. Let f be irreducible and s...
متن کاملHedgehog signaling: cooking with Gas1.
The mechanisms by which morphogens, such as Sonic hedgehog (Shh), specify distinct cell fates in a concentration-dependent manner are not fully understood. Shh signaling is regulated by a feedback network that comprises Shh-binding factors, the expression of which is controlled by the Hedgehog pathway itself. Recent studies have identified the hedgehog-binding protein growth arrest-specific gen...

15 صفحه اولCreating Quanta with 'annihilation' Operator
The non-symmetric nature of the boson 'destruction' operatorâ and its 'creation' partnerâ † is made apparent by applying them to a quantum state |ψ different from the Fock state |n. We show that it is possible to increase (by many times or by any quantity) the mean number of quanta in the new 'photon-subtracted' statê a|ψ. Moreover, in certain cases the mean number of quanta in the (normalized)...
متن کاملSolid aqueous solutions
In most treatments of aqueous "solutions" it is taken for granted that water is present in the liquid state and in excess, with the concentrations of solutes limited by their saturation solubilities. Hence, the thermodynamic reference states are defined as the infinitely dilute solution, a solution of unit molality, etc. In recent years supersaturated aqueous solutions have been receiving incre...
