Optical properties of a phosphor material depend on the nature of the impurity and the site of occupancy of the dopant in the host matrix. In metal silicates with the general formula M2SiO4, there are two cationic sites and, possibility of three diff

We report here on the reorientation dynamics of the avian Red Blood Cell (aRBC), a structure ellipsoidal in shape and with a non-uniform distribution of birefringence across its diameter. We find that in linearly polarized light, an aRBC shows a dual

A dual optical tweezer has been built around an inverted microscope with high numerical aperture objective (N.A 1.4). The setup is versatile and can be used both as a single and a dual tweezer, and in the dual mode, enables us to optically trap two m

A microscopic object finds an equilibrium orientation under a laser tweezer such that a maximum of its volume lies in the region of highest electric field. Furthermore, birefringent microscopic objects show no rotational diffusion after reorienting u

A normal human red blood cell (RBC) when trapped with a linearly polarized laser, reorients about the electric polarization direction and then remains rotationally bound to this direction. This behavior is expected for a birefringent object. We have

We report here on studies of reorientation of human red blood cells (RBCs) in an optical trap. We have measured the time required, t re , for the plane of the RBC entering the optical trap to undergo a 90-deg rotation to acquire an edge on orientatio
