We report on the Raman blue shift of layered MoS2 films as well as an anomalous blue shift of the photo-luminescence spectra of nanocrystallite MoS2 films grown by pulsed laser deposition. Monolayer, bilayer and trilayer MoS2 films were fabricated by ablating MoS2 target for a deposition time of around 14, 24 and 30 s at a laser fluence of 2.2 Jcm(-2). The two Raman active modes showed lattice strain-induced blue shift of 1-3 cm(-1). The layered films showed an out-of-plane compressive strain as well as an in-plane tensile strain confirmed by Riet-Veld refinement of the X-ray diffraction pattern. TEM image of the MoS2 film for 14 s demonstrated the presence of nanocrystallites of an average size of 13 nm along with the layered film of MoS2. An anomalous photoluminescence peak was observed corresponding to the MoS2 nanocrystallites at 2.18 eV, attributed to quantum confinement effect.
