The first observation is reported of the primary and stimulated femtosecond photon echoes at liquid nitrogen and room temperatures in a dye-doped polymer film at a wavelength of 780 nm. Echo signals were generated by pulses with the duration of 65 fs. The primary echo signal decay at liquid nitrogen

The possibility to mechanize at room temperature a logical function of bit-to-bit parallel multiplication for optical echo-processor based on the third-order nonlinear optical response of a resonant medium is experimentally studied. The polyvinilbutural film doped with phthalocyanine dye was used as
It is reported about the first observation (in a solid-state sample) and detailed investigation of the stimulated femtosecond photon echo (SFPE) signals at room temperature in a polyvinylbutural film doped with molecules of phthalocyanine of HW 1009 type at the wavelength of 788 nm. A dependence of
## Abstract The sensitivity of ZnO films, undoped and doped with Er, Ta and Co, to exposure to NH~3~ has been studied. The films were deposited by magnetron coβsputtering of a sintered ZnO target with chips of the different doping elements on its surface. The sensitivities of the ZnO films to expos
Ga doped ZnO (GZO) thin films were deposited on glass substrates at room temperature by continuous composition spread (CCS) method. CCS is thin films growth method of various Ga x Zn 1-x O(GZO) thin film compositions on a substrate, and evaluating critical properties as a function position, which is
