“…As it was shown by the previous studies (Makhniy et al, 2004), the surface modification of the n-CdTe substrates changes their optical properties in a different way depending on the annealing conditions. This approach also works for CdTe:AS and CdTe:O 2 samples featuring a sharp efficiency increase for the edge A-band of luminescence η (Fig.…”

“…The luminescence of the samples was excited with He-Ne and N 2 -lasers (wave lengths 0.63 and 0.337 μm, respectively). The radiation, reflection and transmission spectra (N ω , R ω and Т ω ) were obtained with a universal setup, allowing measurements in standard and differential modes (Makhniy et al, 2004). The spectra were registered automatically with a recording equipment KS-2, also allowing to obtain relaxation curves for the photoluminescence intensity.…”

“…Samples annealed under optimal conditions were selected for further investigations, since they revealed minimal N S and maximal I parameter. The spectra of emission (N ω ), reflectance (R ω ) and transmission (T ω ) were studied with a general-purpose apparatus that enabled performing the measuring process in both conventional and differential modes [8]. The spectra were recorded automatically with the aid of KSP-2 plotter that allowed also recording the relaxation curves of photoluminescence intensity.…”

“…Для проведення відповідних досліджень використовувалася універсальна оптична установка, яка дозво-ляє при однакових умовах проводити комп-лексні дослідження оптичного пропускання, відбивання і люмінесценції. Такі досліджен-ня проводилися як за класичною методикою, так і з використанням модуляційної спектро-скопії (λ-модуляції) [5]. Основними складови-ми установки є спектральний монохроматор МДР-23, система синхронного детектування, галогенна лампа ELC/C з монотонним глад-ким спектром в якості джерела світла, азотний лазер ЛГН-21 (λ = 0,337 мкм) і фотоелектрон-ний помножувач ФЕП-79.…”
