A simple solution combustion route has been used to prepare ZnO nanopowders (NPs) using different barbiturates (Barbituric acid, 1, 3-dimethyl barbiturates and 2-thiobarbiturates) as fuels. The obtained product was well characterized by powder X-ray diffraction (PXRD), scanning electron microscope (SEM), ultraviolet-visible Spectroscope (UV-Vis) and Photoluminescence (PL).

The photometric characterization has revealed the excellent color chromaticity coordinates and the correlated color temperature levels. They are on the same level of commercial phosphors and quite useful for green WLEDs, solid state displays and forensic applications as well.

In addition, lip prints are form of wrinkles and grooves including normal lines, fissures and are present in the zone of transition of human lip between the inner labial mucosa and outer skin. Lip prints are also a main evidence for identification of an individual in a forensic dentistry due to its uniqueness, except in monozygotic twins.

The structural and optical characterization of the nanophosphor is described. The nanophosphor shows a prominent emission in the red region. The concentration dependence of the Pr3þ luminescence is investigated. The Photoluminescence analysis, CIE and CCT coordinates suggest that phosphors derived from LaOF: Pr3þmight a probable application for white LEDs.

The optimized nanophosphors were used to visualize latent fingerprints through recognizing level I-III ridges by a reduced background hindrance and can be utilized for visualizing latent fingerprints on difficult substrate surfaces with superior sensitivity, high contrast and selectivity. Further, a furthermost possible stochastic process to make unclonable anti-counterfeiting tags using optimized nanophosphor was designed to reduce counterfeit products.

In recent times, the crime rate is increasing in the society, and the maintaining of criminal records is becoming essential by locating and tracking each case through latent fingerprint identification along with the imperative of finding the intensity and wavelength via Aggregation Induced Emission (AIE). To meet these demands, we have designed a novel AIE based electron withdrawing moiety such as 2-(4- fluorophenyl)-3H-benzocoumarin.

The year 2004 witnessed what was probably the most highly publicized fingerprint error ever exposed: the case of Brandon Mayfield, an Oregon attorney and Muslim convert who was held for two weeks as a material witness in the Madrid bombing of March 11, 2004, a terrorist attack in which 191 people were killed. Mayfield, who claimed not to have left the United States in ten years and did not have a passport, was implicated in this attack almost solely on the basis of a latent fingerprint found on a bag in Madrid containing detonators and explosives in the aftermath of the bombing.

Several explanations may account for the absence of an initial steep decline in incidence rates. First, the proportion of immigrants who were recently infected or reinfected may already have been low at the time of immigration. Next, the risk of reactivation of latent tuberculosis infection in these immigrants may have been higher than previously modeled in white nonimmigrant populations (8,9).

AFIS systems are amazing. With AFIS, people can be fingerprinted and have their criminal history records checked in a matter of minutes; a mug shot and palm print might be included on the rap sheet returned to the inquiring agency. The technology has moved from exclusively forensic or criminal applications into other areas, such as social services benefits and other emerging applications. The greatest use of AFIS technology is for tenprint identifications, in which rolled fingerprint images are compared against enrolled records.
