Resumen

In this work α-Si₃N₄ coatings grown by hybrid chemical vapor deposition system (HYSY-CVD) are presented. Two different morphologies, pores and fibers, were obtained using two different flows, 45 ml/min (flow 1) and 60 ml/min (flow 2) over a period of 120 min, of nitrogen:ammonia gas mixture (95%:5%). This coatings presents nanocrystals of 20 nm and 36 nm for 1 and 2 flows, respectively, this parameters were obtained by Debye-Scherer formulation. Band gaps of 1.95eV for flow 1 and 1.90 eV for flow 2 were derived from UV-Vis reflectance. The Photoluminescence spectra reveal emissions at 477 nm for flow 1 and 470 nm for flow 2.
